Double object is not initializing as expected
Salman Ahmed:
Hi, I have initialized the double object as:
But when I see it on debugger watch, I get this
what could be the possible reason for getting this small fraction?

Real types (or floating-point types) represent values with a fractional part. In the MQL5 language there are two types for floating point numbers.The method of representation of real numbers in the computer memory is defined by the IEEE 754 standard and is independent of platforms, operating systems or programming languages.

floating point and that some numbers can't be represented exactly. (like 1/10.)
