- I am getting different results when changing the # of digits of precision. For example, 4077 factorial (4077!) gives 8.805358403694188560826142895652149E+12950 with 34 digits of precision is selected but when I change the # of digits of precision to 30 the result is 8.80535840369418856082614289572E+12950 but I would expect it to be 8.80535840369418856082614289565E+12950 based on the result with 34 digits selected.

Could you please tell me which one is the most accurate (the 34 digit result or the 30 digit result)? BTW, I have also seen this happen when switching the # of digits between 34 and 30.

Also, it would be useful to be able to select the desired rounding at the least significant digit. For example, floor, ceiling or round (with midpoint (X.XXXXX5) round up or down).

Thank you in advance! - from Keisan
- 4077! = 8.8053584036941885608261428956521446690495134141499451373172861805330159......E+12950

If the accuracy checkbox is checked, the results are below.

8.8053584036941885608261428957E+12950 (30digit)

8.80535840369418856082614289565214E+12950 (34digit)

- ((1+sqrt(5))/2)^135

The powers of the golden ratio are nearly equal to integers (a so-called "PV number")

[7] 2019/05/19 04:08 Male / Under 20 years old / High-school/ University/ Grad student / Useful /

- Purpose of use
- To confirm the results of an extend precision data type with math functions that I am developing (your website is in the credits). Thank you for providing this extremely useful tool free of charge.
- Bug report
- The answer for a negative value raised to an even power is wrong. For example, -2^2 should be 4, not -4 (just like -2 * (-2), which is correctly calculated as 4). Also, could you please allow copying (so can paste elsewhere) the results in the "Answer" area?
- from Keisan
- -2^2 = 0 - (2^2) = -4

(-2)^2 = 4

Please refer to the page below.
