Error Function Mathematica

I tried playing with setsystemoptions catchmachineunderflow false which however results in getting 0.
Error function mathematica. Erf z is an entire function of z with no branch cut discontinuities. 299 where is a confluent hypergeometric function of the first kind and is a gamma function. 341 define without the leading factor of. Revolutionary knowledge based programming language.
The first few values extended by the definition for and 0 are given by. Erf satisfies the identities. As of version 12 errorlistplot has been superseded by listplot. Mathematical function suitable for both symbolic and numerical manipulation.
Abramowitz and stegun 1972 p. Revolutionary knowledge based programming language. Note that some authors e g whittaker and watson 1990 p. The preeminent environment for any technical workflows.
For certain special arguments erf automatically evaluates to exact values. 0 i for large arguments. Then i tried defining the function as exp log z 2 log erfc i z but this turns out to not be any faster than with automatic switching so it seems hard to speed this up except as daniel lichtblau suggests acl jul 24 11 at 23 46.
