This is useful, for example, in determining the bit error rate of a digital communication system. http://upintheaether.com/error-function/how-to-use-complementary-error-function-table.php Taylor series The error function is an entire function; it has no singularities (except that at infinity) and its Taylor expansion always converges.

To use these approximations for negative x, use the fact that erf(x) is an odd function, so erf(x)=−erf(−x).

## This directly results from the fact that the integrand e − t 2 {\displaystyle e^{-t^ − 2}} is an even function.

If L is sufficiently far from the mean, i.e. μ − L ≥ σ ln ⁡ k {\displaystyle \mu -L\geq \sigma {\sqrt {\ln {k}}}} , then: Pr [ X ≤ L D: A D package[16] exists providing efficient and accurate implementations of complex error functions, along with Dawson, Faddeeva, and Voigt functions.

At the imaginary axis, it tends to ±i∞. Using the alternate value a≈0.147 reduces the maximum error to about 0.00012.[12] This approximation can also be inverted to calculate the inverse error function: erf − 1 ⁡ ( x ) Haskell: An erf package[18] exists that provides a typeclass for the error function and implementations for the native (real) floating point types. The system returned: (22) Invalid argument The remote host or network may be down.

Numerical approximations Over the complete range of values, there is an approximation with a maximal error of 1.2 × 10 − 7 {\displaystyle 1.2\times 10^{-7}} , as follows:[15] erf ⁡ ( J. Hinzufügen Möchtest du dieses Video später noch einmal ansehen?
