There will be some cases where one might not want to show

This function returns a human readable fractional number
in form of fractions and mixed fractions.
Pass in a string, or a number or a float, and this function returns
a string representation of a fraction
or whole number
or a mixed fraction
Examples:
fractional(0.3) will return '1/3'
fractional(1.3) will return '1 3/10'
fractional(float(1/3)) will return '1/3'
fractional(1) will return '1'
This will always return a string.
