Hi everyone, I'm having trouble limiting a double to two decimal places but without rounding it. For example, I'd like to turn this double 0.2298 into this double 0.22
I tried things like: StrToNum(NumToStr(0.2298,4)) but StrToNum won't let you specify how many digits.

jb2080,

when you want to truncate a value basic math seems your best approach. Dividing the integer portion (using the reserved work IntPortion) of your value after you multiplied it with 100 by 100 will give you the result you are looking for.

 

Code

valueToTruncate = 0.2298 ; valueToTruncate = IntPortion( valueToTruncate * 100 ) / 100 ;

It should be noted, that while this will remove the "98" from your value, it will not change the precision of decimal variables or the number of decimal places stored internally by the platform.

Yes!!!! Wow that works great, thanks ABCTG!

number = 0.2298
rounded_number = math.floor(number * 100) / 100
print(rounded_number) # Output: 0.22

This works correctly for me also, thanks!
