explicit conversion to 64-bit real number

Description

( type ) expression

Input

type - 64-bit real number
expression - Expressions

Output

return - 64-bit real number

Note: In C like languages the data type size may be different depending on compiler and architecture, we show only one standard look.

Examples

Explicit conversion to 64-bit real number the possible of use:

double x = 3.14159265359;     // x = 3.14159265359
double y = 123456789;         // y = 123456789.0
y =(double)(x * y);          // y = 387850941.35821074
