Rounding of a field in Internal table

Question

Hi ,
I have a quantity field(menge)  in an internal table( i_tab) . In a loop at the internal table(i_tab) , I want to round off the quantity to x decimal places . 'x' will be different for each record , depending on some logic.
Through what syntax do I achieve this ?

Answer 1

HI,
Using the write statment, you can write the addition  DECIMALS d
<b>Effect</b>
d specifies the number of decimal places for a number field (type I , P or F ) in d . If this value is smaller than the number of decimal places in the number, the number is rounded. If the value is greater, the number is padded with zeros.
Since accuracy with floating point arithmetic is up to about 15 decimal places (see ABAP/4 number types ), up to 17 digits are output with floating point numbers (type F ). (In some circumstances, 17 digits are needed to differentiate between two neighboring floating point numbers.) If the output length is not sufficient, as many decimal places as possible are output. Negative DECIMALS specifications are treated as DECIMALS 0 .
<b>Example</b>
Effect of different DECIMALS specifications:
DATA: X TYPE P DECIMALS 3 VALUE '1.267',
      Y TYPE F            VALUE '125.456E2'.
WRITE: /X DECIMALS 0,  "output: 1
       /X DECIMALS 2,  "output: 1.27
       /X DECIMALS 5,  "output: 1.26700
       /Y DECIMALS 1,  "output: 1.3E+04
       /Y DECIMALS 5,  "output: 1.25456E+04
       /Y DECIMALS 20. "output: 1.25456000000000E+04
<b>and also you can use ROUND</b>
<b>Effect</b>
Scaled output of a field of type P .
The decimal point is first moved r places to the left ( r > 0) or to the right ( r < 0); this is the same as dividing with the appropriate exponent 10** r . The value determined in this way is output with the valid number of digits before and after the decimal point. If the decimal point is moved to the left, the number is rounded.
For further information about the interaction between the formatting options CURRENCY and DECIMALS , see the notes below.
&ABAP-EXAMPLE& Effect of different ROUND specifications:
DATA: X TYPE P DECIMALS 2 VALUE '12493.97'.
WRITE: /X ROUND -2,   "output: 1,249,397.00
       /X ROUND  0,   "output:    12,493,97
       /X ROUND  2,   "output:       124.94
       /X ROUND  5,   "output:         0.12
So, in your Loop, use the WRITE TO statment to move the internal table data with the perfect decimal places for each single field in the loop
