Formatting floats without trailing zeros

Question

How can I format a float so that it doesn\'t contain trailing zeros? In other words, I want the resulting string to be as short as possible.

For example:

<         


        

Answer 1

Here's the answer:

import numpy

num1 = 3.1400
num2 = 3.000
numpy.format_float_positional(num1, 3, trim='-')
numpy.format_float_positional(num2, 3, trim='-')

output "3.14" and "3"

trim='-' removes both the trailing zero's, and the decimal.
