I am a novice in python. I am trying to use the Sellmeier Equation to calculate a refractive index. The coefficients of this equation are decimals to a large number of sig figs ( i.e B1 = 1.03961212, B2 = 0.231792344, C1 = 6.00069867×10−3 ... and so on) in the sellmeier formula there is a lot of fractions, multiplication and squaring of these numbers. I originally state them as floats. However such a process apparently cannot be done with floats like these.

What do i do?

Please need help!

You can use float64 Double precision float: sign bit, 11 bits exponent, 52 bits mantissa. but for this you have to install 64 bit numpy and 

import numpy as np

and you can use: np.float64
