How Can I Eliminate Scientific Notation When Printing Float Values in Python?

Eliminating Scientific Notation in Printed Float Values

When printing float values, scientific notation can be an obstacle, as demonstrated by the following code:

x = 1.0
y = 100000.0    
print(x/y)

The result is displayed as "1.00000e-05," which can be problematic if you intend to use the result as a string.

Suppressing Scientific Notation

Python provides a solution using ''.format, which now specifies the desired number of digits after the decimal. For example:

>>> a = -7.1855143557448603e-17
>>> '{:f}'.format(a)
'-0.000000'

By default, six digits are displayed after the decimal, which may not be suitable for precise numerical values. In such cases, you can customize the display:

>>> '{:.20f}'.format(a)
'-0.00000000000000007186'

Using Python 3.6 String Literals (Update)

Python 3.6 introduces formatted string literals, providing a more concise method:

>>> f'{a:.20f}'
'-0.00000000000000007186'

By utilizing these techniques, you can suppress scientific notation and control the precision of printed float values, ensuring clear and accurate representation for your numerical data.
