Hello, I am completely new to this forum. I am looking for a place to report the following bug in MQL4:
Consider the following simpliflied code:
<CODE REMOVED>
This code will output "false" in the Alert window even though logically it should return true.

double value = 0;
double a = 0;
double b = 0;
double comparison_value = 0;
int start()
{
value = 1.32356000;
a = 1.32357000;
b = 0.00001000;
comparison_value = a - b;
if(value==comparison_value){
Alert("true");
}else{
Alert("false");
}
return (0);
}
//*******************************************************************************
This code will output "false" in the Alert window even though logically it should return true.
setting comparison_value directly to 1.32356000 like this:
comparison_value = 1.32356000;
Will cause the correct response of outputting "true" in the Alert window.
The problem is worked around by putting in this line before the comparison occurs:
comparison_value = StrToDouble(DoubleToStr((next_bar_open + jump_value),8));
The developers of MQL4 should look into this.
The problem occurs not for all numbers but only some combinations of values for "value", "a" and "b".
