Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation.

A Course in Modern Analysis, 4th ed. Erf Table Google search: Google's search also acts as a calculator and will evaluate "erf(...)" and "erfc(...)" for real arguments. The error function at +∞ is exactly 1 (see Gaussian integral). navigate here 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

IDL: provides both erf and erfc for real and complex arguments. Erf(1) Pets Relationships Society Sports Technology Travel Error Function Calculator Erf(x) Error Function Calculator erf(x) x = Form accepts both decimals and fractions. Erf(x) is closely related to the normal probability curve; the cumulative distribution function of a normally distributed random variable X is CDF(X) = 0.5 + 0.5erf[(X-)/σ√2], where is the mean

For previous versions or for complex arguments, SciPy includes implementations of erf, erfc, erfi, and related functions for complex arguments in scipy.special.[21] A complex-argument erf is also in the arbitrary-precision arithmetic However, for −1 < x < 1, there is a unique real number denoted erf − 1 ( x ) {\displaystyle \operatorname Γ 0 ^{-1}(x)} satisfying erf ( erf Weisstein.

Despite the name "imaginary error function", erfi ( x ) {\displaystyle \operatorname 8 (x)} is real when x is real. Julia: Includes erf and erfc for real and complex arguments. The error function, denoted erf, is defined by the integral erf(x) = (2/√π)∫xo e-t2 dt. Computerbasedmath.org» Join the initiative for modernizing math education.

For any complex number z: erf ( z ¯ ) = erf ( z ) ¯ {\displaystyle \operatorname − 0 ({\overline 9})={\overline {\operatorname 8 (z)}}} where z Erf is implemented in the Wolfram Language as Erf[z].
