如何将NumPy数组的元素四舍五入到最接近的整数

在这篇文章中，让我们讨论如何将NumPy数组中的元素四舍五入到最接近的整数。Python的numpy.rint()函数，可以将数组中的元素转换成最接近的整数。

语法： numpy.rint(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj] ) =<ufunc ‘rint’>

示例 1:

import numpy as n
 
# create array
y = n.array([0.2, 0.3, 0.4, 0.5, 0.6, 0.7])
print("Original array:", end=" ")
print(y)
 
# round to nearest integer
y = n.rint(y)
print("After rounding off:", end=" ")
print(y)

输出:

示例 2:

import numpy as n
 
# create array
y = n.array([-0.2, 0.7, -1.4, -4.5, -7.6, -19.7])
print("Original array:", end=" ")
print(y)
 
# round to nearest integer
y = n.rint(y)
print("After rounding off:", end=" ")
print(y)

输出:
