How do I get around this error using the eval statement? I DO NOT want to make the field bigger, I just want to truncate the extra decimals.
Huh? Do you mean that you want to truncate the extra digits? Truncating extra decimals is not necessary, it happens automatically.
For example, the following code won't receive any errors, in spite of the fact that it drops a decimal place:
midrange.com
D A s 5P 1
D B s 5P 1
/free
a = 0.5;
b = a / 2;
It is a complex equation, which I then push the result to a display field, so to determine the max field size will be difficult, plus I then have to move the 'temp' field to a display field.
If the max field size is a really big issue for you and you don't care about losing accuracy (which is very unsual for an RPG programmer, I might add!) you might consider using floating point fields. They allow for extremely huge numbers or extremely low numbers without a need to know ahead of time how many digits/decimals are needed.
The drawback is that they can lose accuracy. The result will be close, but might not be exact. Since you're not worried about digits being lost, I assume that you don't care if your result is exact -- so this might be a good solution.
I just want to ignore the extra decimals! I tried eval(r) also and still get the same errors
I don't understand what eval(r) has to do with your question. Are you having trouble with an intermediate result? If that's the case, you could try using %DEC() to control the intermediate result size.
