How to Avoid Scientific Notation When Printing Floats in Python?

Suppressing Scientific Notation in Float Value Printing

In Python, printing float values using the print function may result in scientific notation, especially for very small or large values. This can be problematic if you want to use the result as a string.

For instance, consider the following code:

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

This code will print 1.00000e-05, which is in scientific notation.

To suppress scientific notation and display the value as 0.00001, you can use the .format method of strings. This method allows you to specify the format of a floating-point number, including the number of decimal places to display.

For example, you can use the following code to display the quotient with four decimal places:

formatted_quotient = '{:.4f}'.format(x / y)
print(formatted_quotient)

This will print 0.0000, as desired.

Another option available in Python 3.6 and later is to use formatted string literals (f-strings). These allow you to specify the format of a floating-point number directly in the string literal:

formatted_quotient_f = f'{x / y:.4f}'
print(formatted_quotient_f)

This will also print 0.0000.
