public static method LerpUnclamped(a: float, b: float, t: float): float;
public static float LerpUnclamped(float a, float b, float t);

## Parameters

 a The start value. b The end value. t The interpolation between the two floats.

## Returns

float The float value as a result from the linear interpolation.

## Description

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.
