You are doing Integer division. Use floating point division by making at least one of the numbers floating point:
Average = (256.0 / 5 ); Average = (256 / 5.0); Average = (256.0 / 5.0);

Please understand that dividing by 100 or dividing by 100.0 will give totally different results.
In the former, 100 is considered an Integer literal constant and so it will carry out integer division which will truncate the decimal values.
In the latter, 100.0 will be considered a floating-point literal constant and it will carry out floating-point division which will keep the decimal values.
This is the principal behind the problems you are having. So, to prevent this, either use a floating-point literal constant or typecast the variable into a (double).
Example:
Print( "90 / 100 = ", 90 / 100 ); Print( "90 / 100.0 = ", 90 / 100.0 ); Print( "90.0 / 100 = ", 90.0 / 100 ); Print( "90.0 / 100.0 = ", 90.0 / 100.0 );2021.07.23 21:26:57.060 TestCopy EURUSD,H1: 90 / 100 = 0 2021.07.23 21:26:57.060 TestCopy EURUSD,H1: 90 / 100.0 = 0.9 2021.07.23 21:26:57.060 TestCopy EURUSD,H1: 90.0 / 100 = 0.9 2021.07.23 21:26:57.060 TestCopy EURUSD,H1: 90.0 / 100.0 = 0.9

OK. But that division was just an example to illustrate the problem. In the actual code, I don't provide the numbers.
For example, a certain number of bars are found that will meet a certain condition. Then I want to get the average number of bars that meet the condition:
double Average = (Bars / Found);
Both numbers will be integers.
Typecast them into floating point — Typecasting - Data Types - Language Basics - MQL4 Reference
double Average = (double) Bars / Found; double Average = Bars / (double) Found; double Average = (double) Bars / (double) Found;

256 divided by 5 is 51.2, but MT4 gives me 51.00000000.
Why is that?
