Float to 3 decimal places as a string

EasyString Programs · 41 of 106

Write a Python program to format a float to 3 decimal places and convert it to a string.

Input

2.14652

Output

2.147 str

Approach

Use the format spec .3f.

Solution

Python

x = 2.14652text = f"{x:.3f}"print(text, type(text).__name__)

Output

2.147 str

Note

Formatting rounds, so 2.14652 becomes “2.147”, not “2.146” as the original sample showed. Use str(int(x * 1000) / 1000) if you need to cut off digits instead.
