MQL5 devision returns zero ?

[Robert hofer]

hi

Look at this part of code. It prints 0. I don't know why!

Any idea?

int  risk_percent = 10;
   
Print(risk_percent/100);

0.1 is 're-converted' to an int and so 0.1 becomes a rounded 0.

I changed variable type to 'double' and problem solved! thanks!!

You have the right idea, but no it never gets re-converted. It remains an integer during the entire process. It carries out integer division, not floating-point division.

In integer division, if the divisor is greater than the numerator, then the results are always 0.

int  risk_percent

Of course, it does.
