- 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.
