Just checking an algorithm I stumbled on a slightly interesting result. The expression is
5/(1.5**4).
Needs answer to 9 decimal points.

And you only need one decimal place for the answer.My old favorite from back in the heyday of the hand calculator is 987654321 ÷ 123456789.
OK, you only need 1 decimal place for a engineering answer.\(\frac{987654321}{123456789}=8.000000072900000663390006036849\)
Just curious. What did you use to get that many digits? Excel drops anything past 729. Another calculator I have gives ...72900001 using double precision and ...72900000664 using float80.\(\frac{987654321}{123456789}=8.000000072900000663390006036849\)

Yes, that's why I said to 9 decimal digits of precision. The repeat count gets approximated.\(x=\frac{5}{1.5^4}\)

The M$ calculator can handle more than 8 digits.

Ah, so Windows calculator. I gather it uses bignum (precision limited by system memory), so that would do it.
