Check Datatype whether is Integer or decimal

fcjHH

How it be examined can whether the result of a formula is a whole number or right-of-comma positions contained? :?

I do not understand what you want... please be more specific...

result type is based on operators used and on used variables...


1 / 2 = decimal
1 div 2 = integer


for example...

i have this example:
2500 / 500

now i want to check, if the result is an integer or a decimal.
if it's an integer, i have to do something different, if it's a decimal with 1 or more decimal-places i can do another step.

i tried it: Variable XXX as variant an the code: ok := xxx.isinteger
but if the result is 4, this does not recognize it as an integer.

:?:

more ways:

  if XXX = ROUND(XXX,1) then
    Message('Is integer')
  else
    Message('Is Decimal');

  if (XXX / YYY) = (XXX div YYY) then
    Message('Is integer')
  else
    Message('Is Decimal');

it depend on what you have...

An other way:

if (x mod 1) <> 0 then
there is an remainder

expl.:
x := 85.3;
x mod 1 = 0.3

or try using the EVALUATE function

IF EVALUATE(IntVar,Result) then
integer
ELSE
decimal;
