Summary

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

Returns the greater of two arbitrary values
Returns a float

• float x
• float y

If values x and y are equal, returns x

See also: Min

Specification

<lsl>float max(float x, float y) { 

   if( y > x ) return y;
   return x;

}</lsl>

Examples

<lsl>float value = max(10,20); //value == 20</lsl>
