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
