float2::ScaledToLength

Syntax

float2 float2::ScaledToLength(float newLength) const; [8 lines of code]

Returns a scaled copy of this vector which has its new length as given.

This function assumes the length of this vector is not zero. In the case of failure, an error message is printed, and the vector (newLength, 0) is returned.
