c# - Combine two integers (one containing the integer part, the other the decimal part) into a floating point number

Question

How do I produce a double value by combining two integers? I already tried searching but I can't find the answer that I'm looking for.

It goes like this:

int wholeNumber = 2;
int decimal = 25;

I want to make a double that results into 2.25.

Answer 1

Cheating solution goes like this:

string number = wholeNumber + "." + decimal
double doubleNumber = Double.Parse(number);

Clean solution would involve checking how many values you have in the 'decimal', dividing by 10^amount and adding them

As was pointed out - decimal seperator is cultural-specific - so the completly correct version is

string number = wholeNumber + System.Globalization.CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSepar??ator + decimal
double doubleNumber = Double.Parse(number);

(I kept the top one because its easier to understand)
