Text code interpreted as scientific notation

Question

I have an http service returning xml to populate a data grid.
The grid columns are tied to element attributes. One of these
columns is a simple text code, like a product code. When this
product code "looks like" scientific notation (e.g. "3E5"), the
grid is displaying "300000" instead of the code. Is there a way
somehow to tell the grid that this is a text field, and not a
number? How do you turn this off? I am rendering the column with a
label, but it doesn't make any difference. Thanks for any
tips.

Answer 1

Is from trying to jam an int into float?That's exactly the cause. Here are some solutions:
- Use java.text.DecimalFormat to format the output or cast the float to an integer type when you want to print it (presicion might become a problem).
- Keep the number in an int or long all the time. This way you'll not lose any presicion.
Explanation can be found in the API docs of Float.toString():"If the argument is NaN, the result is the string "NaN".
Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '-' ('-'); if the sign is positive, no sign character appears in the result. As for the magnitude m:
If m is less than 10^-3 or not less than 10^7, then it is represented in so-called "computerized scientific notation." Let n be the unique integer such that 10n<=m<1; then let a be the mathematically exact quotient of m and 10n so that 1<a<10. The magnitude is then represented as the integer part of a, as a single decimal digit, followed by '.' (.), followed by decimal digits representing the fractional part of a, followed by the letter 'E' (E), followed by a representation of n as a decimal integer, as produced by the method Integer.toString(int) of one argument."
