Cast

Description

The cast operator translates one variable type into another and forces calculations to be performed in the cast type.

Syntax

(type)variable

Parameters:

type: any variable type (e.g. int, float, byte)

variable: any variable or constant

Example

int i;
float f;

f = 3.6; 
i = (int) f; // now i is 3

Note

When casting from a float to an int, the value is truncated not rounded. So both (int) 3.2 and (int) 3.7 are 3.
