How Can I Suppress Scientific Notation When Printing Floating-Point Numbers in Python?

Suppressing Scientific Notation in Python

When working with floating-point values, you may encounter scientific notation (e.g., 1.00000e-05) when printing the results. This can be undesirable, especially if you need the result as a string with a specific format.

Problem:

Consider the following code:

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

The quotient displays as "1.00000e-05," using scientific notation. You want to suppress this notation and display it as "0.00001" as a string.

Solution:

Using the ''.format() Method:

To suppress scientific notation using ''.format(), use the ".f" specifier. This specifier allows you to specify the number of decimal places to display. For example:

print("{:.5f}".format(x/y))

This will display the quotient as "0.00001."

Using Formatted String Literals (Python 3.6 ):

In Python 3.6 and later, you can use formatted string literals to simplify the process. The syntax is as follows:

print(f"{x/y:.5f}")

This achieves the same result as the ''.format() method.

Example:

x = 1.0
y = 100000.0
result = f"{x/y:.5f}"
print(result)

Output:

0.00001

By using these methods, you can suppress scientific notation when printing floating-point values and obtain the desired string format.
