expm1f

Description:

public float expm1f (float x)

Returns a value equivalent to exp(x) - 1.

Note:

Remember to link the math library: valac -X -lm ...

It is computed in a way that is accurate even if the value of x is near zero; a case where exp(x) - 1 would be inaccurate due to subtraction of two numbers that are nearly equal.

Parameters:

x	A numeric value
