- Intermediate levels of Re(ƒ)=constant are shown with thin red lines for negative values and with thin blue lines for positive values.
- When x is close to 1, then 1 - x is a small number and might be rounded down to 0.

It is related to inverse erf by (2) It has the special values (3) (4) (5) It has the derivative (6) and its indefinite integral is (7) (which follows from the Erfinv Excel Wolfram|Alpha» Explore anything with the first computational knowledge engine. The Maclaurin series of is given by (15) (OEIS A002067 and A007019). http://mathworld.wolfram.com/InverseErfc.html erf(x) = GammaDist(x^2,0.5,1,True) so erfinv(p) = Sqrt(GammInv(p,0.5,1)) erfc(x) = ChiDist(2*x^2,1) so erfcinv(p) = Sqrt(ChiInv(p,1)/2) The ChiDist function is much more accurate for large x than the ATP erfc function.

Excel: Microsoft Excel provides the erf, and the erfc functions, nonetheless both inverse functions are not in the current library.[17] Fortran: The Fortran 2008 standard provides the ERF, ERFC and ERFC_SCALED this contact form MathCAD provides both erf(x) and erfc(x) for real arguments.

IDL: provides both erf and erfc for real and complex arguments. For complex double arguments, the function names cerf and cerfc are "reserved for future use"; the missing implementation is provided by the open-source project libcerf, which is based on the Faddeeva Erfc(1) There is also a CONFIDENCE function.
