Rounding Decimals

In NumPy, there are five primary methods for rounding off decimals:

Eliminate the decimals and return the floating-point number closest to zero by using the trunc() and fix() functions.

Truncate the elements of the following array:

import numpy as np

arr = np.trunc([-3.1666, 3.6667])

print(arr)

Using the fix() function with the same example:

import numpy as np

arr = np.fix([-3.1666, 3.6667])

print(arr)

The around() function increments the preceding digit or decimal by 1 if it is greater than or equal to 5; otherwise, it leaves it unchanged.

For example, rounding $3.16666$ to one decimal place results in $3.2$ .

Round $3.1666$ to two decimal places:

import numpy as np

arr = np.around(3.1666, 2)

print(arr)
