How do you convert a float to an integer?

Since a float is bigger than int, you can convert a float to an int by simply down-casting it e.g. (int) 4.0f will give you integer 4. By the way, you must remember that typecasting just get rid of anything after the decimal point, they don’t perform any rounding or flooring operation on the value.

What is float in C program?

Float is a shortened term for “floating point.” By definition, it’s a fundamental data type built into the compiler that’s used to define numeric values with floating decimal points. C, C++, C# and many other programming languages recognize float as a data type. Other common data types include int and double.

Is integer and float equal?

So as long your floats come from non decimal literals, the comparison with the equivalent integer will be the same, because the integer will be cast to the very same float before the comparison can be done.

How does C# convert float to int?
