- Comment/Request
- What is this value "t" in this function.? I didn''t find any explanation anywhere

- Purpose of use
- For a side problem in nonlinear curve fitting. I didn''t feel like using Excel

- Purpose of use
- academic assignment
- Comment/Request
- huh, i was using this to check an assignment using a taylor series approximation and i think i found a misprint in my textbook's function when i checked it against this and another source's taylor series approximation

- Purpose of use
- I wanted to verify that I was using the Excel "erf.precision" function correctly, so I used this website to cross-check the Excel result.

- Purpose of use
- Use to check my own error function calculator. Amassed to see almost the same results.
Slight differences after 6 decimal, which i want to believe aren't a big deal. - Comment/Request
- I would also want to know the exact formulas used.... especially for numbers greater than 5.

- Comment/Request
- hello
I want to ask about error function how I can find the error function if it was mulitiyplay by value like erf(tX)
and thank you very much

- Purpose of use
- Created a rational approximation method like the Abramowitz & Stegun with 13 terms which I think is good to 10**(-12). Checked it against brute force computations using power or asymptotic series. The brute force method, which is very fast by the way, (up to 600 terms) checked favorably with your computations. Could use a long table to verify the rational approximation accuracy.
