Convert a Double into an Int

Convert a Double into an Int

There are many things you can do to convert a float to an int depending upon what results you expect. If you want to use the built-in language conversions, you can simply assign the float to an integer. For example: float f = 9.99;int i;i = int(f); // conversion.. truncates.This will truncate the value and always return the integral part. Also, notice that the typecast to int was not really necessary, but I like to write it explicitly to make my intentions well-known. If you want to achieve something with the conversion other than the standard behavior, you will have to use functions from the standard C++ or C library. Two useful functions are floor and ceil. Both of these return float, but the value can be used as an integer.
