6.7x10^(-16) / (1 + 6.7x10^(-16))

If I do an order of magnitude approximation, then the bottom becomes 1, but that will make the top zero since we are assuming 6.7x10^(-16) to be zero.

Any ideas on simplifying this?

[tex]\frac{6.7 x 10^{-16}}{1 + 6.7 x 10^{-16}} = \frac{6.7}{10^{16} + 6.7}[/tex]

by multiplying the numerator and denominator by 10

If you want the exact value, divide 6.7 by 10000000000000006.7, either by long division or a calculator that can handle this many significant digits.

Why do you need this much precision, though?

Thank you for the reply. My calculator and Mathematica didn't want to spit out that many digits.

Consider this thread solved.
