Cast a float value to an integer value, this method simply removes the number fractions, so for example [code]int(2.7)[/code] will be equals to 2, [code]int(.1)[/code] will be equals to 0 and [code]int(-2.7)[/code] will be equals to -2.
Cast a float value to an integer value, this method simply removes the number fractions (i.e. rounds [code]from[/code] towards zero), so for example [code]int(2.7)[/code] will be equals to 2, [code]int(0.1)[/code] will be equals to 0 and [code]int(-2.7)[/code] will be equals to -2. This operation is also called truncation.
