If maxval is specified, it is taken to be the maximum intensity value or V. If no value is specified for maxval, its value is determined from the input type, so V may encompass a larger range than 0-1. HSV values range from 0.0 to 1.0, so the return value has a type of FLOAT, unless maxval is not specified or the input type is not byte, where V may be a larger range than 0-1.
