Converting string to float number

Here's what I'm trying to do. The user types a number, such as 12.011, in an input box. I want to check to see if the number they typed is between two numbers, such as 12 and 12.1. Therefore, I want to convert the string in the input box to a float number, not an integer, so I can check to see if it's in the correct range. How do I convert a string into a float number?
thanks
Mark

Did you try:
Number(textinput1.text);
if(Number(textinput1.text)>12 && Number(textinput1.text)<12.1)

Not able to convert string attribute to number and date please help me out

not able to convert string attribute to number and date attribute. While using string to date conversion it shows result as failure.As I am reading from a text file. please help me out

Hi,
You need to provide an example value that's failing and the date formats in the reference data you're using. It's more than likely you don't have the correct format in your ref data.

Appears to be right, but don't forget to round to the nearest integer.

Converting string to float

I have a decimal string "122339994" which i am trying to convert to float using Float.parseFloat. This results in incorrect value of 1.22339992E8.
I thought for floats precsision comes into effect after decimal places.
public static void main(String[] args) {
String floatString = "122339994";
float floatNumber = Float.parseFloat(floatString);
System.out.println("Float is "+floatNumber+". Now double "+Double.valueOf(floatString));
}

See this API
[Java2SE Float|http://download-llnw.oracle.com/javase/6/docs/api/java/lang/Float.html#valueOf%28java.lang.String%29]
Note that trailing format specifiers, specifiers that determine the type of a floating-point literal (1.0f is a float value; 1.0d is a double value), do not influence the results of this method. In other words, the numerical value of the input string is converted directly to the target floating-point type. In general, the two-step sequence of conversions, string to double followed by double to float, is not equivalent to converting a string directly to float. For example, if first converted to an intermediate double and then to float, the string
"1.00000017881393421514957253748434595763683319091796875001d"
results in the float value 1.0000002f; if the string is converted directly to float, 1.0000001f results.

How to convert timing to floating number

hi everyone, i want to do a time measurement of hall sensor and use this value to set a frequency and also to use as process value in a PID controller. the problem is that i get an dynamic data output and i'd like to have this in a floating number, is this possible? or another way is also good... hereby a jpeg to make it more clear.
i also get more problems with this, when i change the throttle (0-100%) is doesn't do anything and my while loop also doesn't end anymore. this is just a small part of the complete program, maybe it's to heavy for my comp? (single core 1,6Ghz, 1,5gig ram)
hope it's a little bit clear what i mean
thanks in advance !
P.S: i know that the divide by one is useless because you can directly measure the frequency, this has allready changed.
the program is meant to drive a PMSM motor
Solved!

hi thanks for the reply, the answer you gave helped me out.
now i've noticed that when i ad the the pid loop (even when nothing of it is connected) the program doesn't respond anymore. is this because of my computer? the while loops (both the normal and pid loop) are stopped by a single switch...
i have uploaded my VI so maybe someone could check it out, be aware it's totally not finished ^^. if you delete the pid control you'll see what i mean.
thanks in advance

UCCX: unable to convert string into a number

Hi all,
I used the Get Digit String to pull a 4 digital numbers (stored as variable sYear) from a caller, this number is obviously stored as a string. Then i used 'set iYear=sYear' to conver this string to an integer.
I debuged the script, when I entered number of year without following #, it worked fine. If I entered number of year and followed by #, i got the message 'unable to conver string into a number'. Can someone help me with that?
Thanks a lot.

Hi Reena,
The UCCX version is 10.5.1.
I found the problem. It works after i changed input length to 5. 'The terminating key overrides the Maximum Input Length to terminate input'.
Thanks.

Convert string to float

It seems extremely rudimentary but I haven't been able to find an answer yet.
I would like to pass in a string representing a human-readable floating point (ie, non IEEE 754) and get its value.
A straight up assignment of a string variable into a f variable doesn't work for thousand dividers. We would also need it for every scenarios:
123.456
123,456
123456
123456,789
123.456,789
123,456.789
all should be valid inputs and the resolution should be dependent on system setting for number formats.
I would like a built-in ABAP call with no manual processing. I'm sure this problem has been encountered thousands of times and solved thousands of times. No point reinventing the wheel.

Tested Code
Output as below
String : 123,456,789,123.456
String : 123456789123.456
Float : 1.2345678912345599E+11

Problem in Converting string to float

Hi,
I am reading from textField and trying to convert that string value to float.
Compiler is giving error cannot find symbol toFloat even though I have included java.lang in my program.
Please help me with this one.

Use
float f = Float.parseFloat(inputString); //where inputString is the string you want to parse

Converting strings to the floating number and plotting

Hello,
I have a question regardting converting string of numbers to the floating bumbers and plot for voltage vs. weight.
The load cell for the ADC resolution is 16 bits, and the voltage will be in between +-5 volts.
The problem, I have the most is converting the string of numbers to the floating numbers, in my case is the weight.

When you say "string of numbers" do you mean an array? What is the specific issue you are having? You seem to have orange wires running all over the place. Give a small example demonstrating the problem.

Expression Builder: convert string to number

Hi all,
I'm having trouble building a field validation rule for bank account numbers.
The numbers have 12 positions, so I cannot use a string or text number.
The validation rule to be implemented is that the last two digits are calculated based on the first 10 (modulo 97).
However, when I use the Mid function to pick the first characters, I am unable to do any calculations on it. Apparently, the string to number conversion doesn't work (it should work when I read the manual, as it says that when using an operator between two data types, the second type is converted to the first (cf. example of 1234+abcd (should result in 1234 as to the manual))). So I tried '1*Mid(...)' or '0+Mid(...)'. Syntactically the expression builder accepts it and I can save it. BUT when I change the particular value on the screen, it gives me an SSO error (not the Field Validation error message I entered).
Why isn't there simply a function ToNumber (like ToChar)????? How could I workaround this?
Any input very welcome!
Frederik

Apparently, I was a bit confused when typing the first sentence, it should be:
The numbers have 12 positions, so I cannot use an integer or number data type, but have to use String.

Essbase 9.3 Calc scripts. Pb with dates. How to convert (string = number) ?

Hello,
I've a problem with Essbase(Planning?) Scripts on version 9.3. It looks simple but I do not find any (clean) solution :
On my Essbase database, I have a member called "Reference_Date" on my axis Indicators. It is a date data type, that is to say, it displays a number corresponding to a YYYYMMDD format. For example : 20091029 for October 29th 2009.
In calc scripts I often need to compare the month included in that "Reference_Date" with the current Member of my Time Axis (I have 12 Months members based on the format M02 for February for example). The final aim is to calculate a number of complete years since that "Reference_Date".
But theses two elements are not of the same "type" (one is a number value and the other is a "member" in Time Axis). So I'm forced to convert one of this two elements in order to compare it.
For example I can extract the month value of the "Reference_Date"' and put an "M" before it to have a Time member equivalent or I can convert the member Name M10 to a number (10))
in both cases I have the same type problem : I don't know how to convert a string into a number nor how to convert a number into a string.
(For example @CONCATENATE doesn't work with numbers). and that my only remaining problem.
I didn't find any Essbase Function which do this (conversion number <=>string).
Is anyone have an Idea ?
Thanks for your help
Best regards

I don't know any way for you to compare your data against your metadata. Not directly. To me it makes little enough sense to try that I'm not surprised the developers didn't provide for it.
I've converted member names to strings, manipulated the strings (calc script functions are not good at this), and turned them back into member names, but that's really the only use I've had for string manipulation. I don't think an equivalency operator even exists for string data. And I see no way to begin thinking of a member name, once converted to a string, as a number.
It makes even less sense to me to try thinking of a data value as a string. Even text values in Sys 11 are stored as numbers. Not encoded characters, but just a number to look up somewhere.
I think you can do what you want though, with something like this...
IF (@ISMBR("FY08"))
vYr = 2008;
ELSEIF (@ISMBR("FY09"))
vYr = 2009;
ENDIF;
IF (@ISMBR("M01"))
vMth = 1;
ELSEIF (@ISMBR("M02"))
vMth = = 2;
ENDIF;
"Years_Since_Reference" = ((vYr * 100) + Mth) - ("Reference_Date" / 12);
Obviously, the math will need some work, coz that doesn't actually work, but the logic above essentially turns your metadata into numbers, which is what you are after.
Good luck,

Convert from String to float

How do I convert from String to float?

Hi,
you can use a Double for example - assuming value is that string to parse
float f;
try { Double d = new Double(value); f = d.floatValue(); }
catch (NumberFormatException e) { f = 0.0; } // error - string value could not be parsed
// here use your float fHope, that helps
greetings Marsian
P.S.: the Double class is usefull for that, because you also can get intValue(), doubleValue() or longValue() out of it for example. The StreamTokenizer for example parses numbers also only to double.
