| a | The start value. |
| b | The end value. |
| t | The interpolation between the two floats. |
float The float value as a result from the linear interpolation.
Linearly interpolates between a and b by t with no limit to t.
The parameter t is not clamped and a value based on a and b
is supported. If t is less than zero, or greater than one, then LerpUnclamped
will result in a return value outside the range a to b.
Suppose parameter a = 0.33f, and b = 1.5f. If interpolator t = -0.25f then the return
value is 0.0375f.
Details: The calculation (b - a) is 1.17f. This is scaled by 0.25f and a result of
0.2925f is obtained. Subtracting this from a (because the interpolant t is negative)
results in 0.0375f.
