How Can I Prevent Scientific Notation When Printing Floats in Python?

Suppressing Scientific Notation in Float Value Printing

In Python, floats with very large or very small values are often represented in scientific notation. While this is useful for scientific applications, it can be undesirable in scenarios where precise and easy-to-read values are required. If you need to suppress scientific notation and display the value as a regular decimal number, consider the following solutions.

Using the ''.format() Method

The ''.format() method allows you to specify the formatting of floating-point values. To suppress scientific notation, follow these steps:

1. Use '{:.nf}' format string, where n is the number of digits you wish to retain after the decimal point.
2. Surround your number with quotation marks, e.g., "{:.6f}".format(my_float).

Using Formatted String Literals (Python 3.6 and Later)

In Python 3.6 and later, you can use formatted string literals (f-strings) for simpler and more concise code:

1. Use the f-string notation, e.g., f'{my_float:.6f}'.
2. The number after the colon (.) specifies the number of digits after the decimal point.

Example:

Consider the following code:

x = 1.0
y = 100000.0
quotient = x / y
string_quotient = f'{quotient:.6f}'
print(string_quotient)

Output:

0.000010

This code uses f-strings to suppress scientific notation and display the quotient as a decimal value with 6 digits after the decimal point.
