The package can use numba to increase speed of the calculations. If you want to install it with numba, you can use the following command:

pip install math-rounding[numba]

or just install numba separately.

Usage

The main function of the package math_rounding has the following signature:

def math_rounding(n: Number, p: int = 0) -> float:
    ...

where:

• n is the number to round;
• p is integer number that specifies the position to which rounding will be performed.

p could be a positive number or a negative number. It represents the position in the number from the dot:

• when it's equal to 0 (default), the rounding will be performed to integer;
• when it's positive, it represents the position in fractional part of the number;
• when it's negative, it represents the position in integer part of the number.

Example

from math_rounding import math_rounding

print(math_rounding(0.5))      # 1.0
print(math_rounding(-0.5))     # -1.0
print(math_rounding(1.1))      # 1.0
print(math_rounding(0.05, 1))  # 0.1
print(math_rounding(5, -1))    # 10.0
print(math_rounding(15, -1))   # 20.0
