97 [expression ['erfc(-z) = 2 - erfc(z);] // preferred when -z < -0.5]
99 [expression ['erfc(-z) = 1 + erf(z);] // preferred when -0.5 <= -z < 0]
116 disappear from the result. As a result the error for erf and erfc in this
122 [expression ['erfc(z) * exp(z*z) * z ~ c]]
126 Therefore for `z > 0.5` we calculate `erfc` using:
128 [expression ['erfc(z) = exp(-z*z) * (C + R(z - B)) / z;]]
131 the average of `erfc(z) * exp(z*z) * z` taken at the endpoints of the range.
141 [expression ['erfc(z) = exp(-z*z) * (C + R(1 / z)) / z;]]
