min

Summary

Function: float min( float x, float y );

Returns the lesser of two arbitrary values
Returns a float

• float	x
• float	y

If values x and y are equal, returns y

See also: Max

Specification

float min(float x, float y)
{
    return ( ( llAbs( x >= y ) ) * y ) + ( ( llAbs( x<y ) ) * x );
}

Examples

float value = min(10,20); //value == 10
