I'm trying to subtract two values and it is giving me different results
Hello,
Right now I have two values for the high and open for the last bar but when trying to subtract them it gives very different results and I have trying for hours to discover why this happens with no luck :(. I'm a beginner so i know I'm missing something.
HIGH OPEN
113.4999999999995 ---- 113.3999999999995
The two values are stored in variables but when subtracting the variables I got this.
EXPECTED RESULT : 0.1000000000000085
THE RESULT I GOT : 0.09999999999999432

Floating-point has an infinite number of decimals, it's you, not understanding floating-point and that some numbers can't be represented exactly. (like 1/10.)
Double-precision floating-point format - Wikipedia
See also The == operand. - MQL4 programming forum (2013)
If you want to see the correct number of digits, convert it to a string with the correct/wanted accuracy.

It's normal, floating point variables have limited precision.

Okay I didn't understand everything but I do the same code in python and it returns " 0.1000000000000085 " while it returns " 0.09999999999999432" on mql4 so how can i get the same result on mql4 or at least get the opposite result in python as i want the two answers to be uniform.
also i didn't mention that the variables are declared as doubles.
Thank you.
