[Solved] How can I find the amount of numbers in double?

by


This won’t end up well. The problem is that sometimes there are float errors when representing numbers in binary (which is what your computer does).
For example, when adding 1 / 3 + 1 / 3 + 1 / 3 you might get 0.999999… and the number of decimal places varies greatly.

ravi already provided a good way to calculate it, so I’ll provide a different one:

double number = 0; // should be equal to the number you want to check
int  numFloating = 0;
while ((double)(int)number != number){
    number *= 10;
    numFloating++;
}

number is a double variable that holds the number you want to check for decimal places.
