If you don't have access to an error function calculator such as the one above, you can approximate the function with the formula The error function can also be expressed with Error Function Calculator Casio

That way you can make an appropriate trade off of precision versus speed. TOPICS ABOUT HOMECALCULATORS Academics Arts **Automotive Beauty Business** Careers Computers Culinary Education Entertainment Family Finance Garden Health House & Home Lifestyle MAKE IT! The error function, denoted erf, is defined by the integral erf(x) = (2/√π)∫xo e-t2 dt. this page Most languages seem to have a way to link in C functions, and if that is the case, then there is an open source implementation somewhere out there.

Other than that, I would try the Taylor series. Normal Distribution Calculator They use their implementation **of the incomplete gamma function, which** in turn uses a mixed approach depending on the argument. When stating a theorem in textbook, use the word "For all" or "Let"?

Which method you use for which intervals is down to experimentation. –Tim Seguine Sep 1 '11 at 10:51 A lot of this comes down to the desired accuracy and Gaussian Calculator M.

Properties and Equations The values of x for which x = erf(x) are approximately 0.6175 and -0.6175. asked 6 years ago viewed 6131 times active 1 year ago Get the weekly newsletter! share|cite|improve this answer answered Jul 20 '10 at 22:38 Isaac 26.8k872122 add a comment| up vote 2 down vote Here's a link to the boost c++ math library documentation.

Enter the minimum and maximum for the X-axis and for the Y-axis. If you size it properly, then the function will appear constant with respect to your machine precision outside of this interval. For larger values you could use the asymptotic series. The function rapidly converges to its asympotic values; erf(3) = 0.99998 and erf(-3) = -0.99998.
