Returns the exponent value to apply to the output value from the
source module.
@returns The exponent value.
Because most noise modules will output values that range from -1.0
to +1.0, this noise module first normalizes this output value (the
range becomes 0.0 to 1.0), maps that value onto an exponential
curve, then rescales that value back to the original range.
