Percentage calculation in cobol

Hi ,

i need to calculate Not found records percentage in my cobol program.

i have following fields:

not-found-rec-count pic 9(09).
Total-rec-count pic 9(09).
Mis-match-percent pic 9(03).

i have done below computation to get the mis-match percent.

Compute Mis-match-percent = (not-found-rec-count/Total-rec-count) * 100

But some times it is not giving percentage properly.

can any one tell me the solution for this.

Hello,

Please post a few sets of "input", the result of the calculation using that input and what you would rather see as the result. You might create a bit of code to do nothing but process a few sets of "counts" and display the values - no need to actually read the data, especially if the number of records might approach a billion (pic 9(9) is a very large number of possible records which is very, very rare). The size of the accumulators may also cause your calculation problems.

For starters, you should have some decimal positions defined in one or more of the fields used in the calculation. If the final result is to be without decimals, i'd suggest rounding the result.

Hello,

While waiting on some longer running processes, i did a little experiment.

If you define the first 2 fields as 9(9) and the percent field as 9(3)v999, you will get better results. When i used your definitions, i got a pct of zero.

This worked
