Python math.fabs()方法 (Python math.fabs() method)

math.fabs() method is a library method of math module, it is used to get the absolute value of a number, it accepts a number (that can be either positive integer/float or negative integer/float) and returns an absolute value in the float type.

math.fabs()方法是数学模块的库方法，用于获取数字的绝对值，它接受数字(可以为正整数/浮点数或负整数/浮点数)并返回绝对值在浮点类型。

Syntax of math.fabs() method:

math.fabs()方法的语法：

    math.fabs(n)

Parameter(s): n – a number or a numeric expression.

参数： n-数字或数字表达式。

Return value: float – it returns a float value, which is an absolute value of given number/numeric expression n.

返回值： float-返回浮点值，它是给定数字/数字表达式n的绝对值。

Example:

例：

    Input:
a = -10
b = 10.23
# function call
print(math.fabs(a))
print(math.fabs(b))
Output:
10.0
10.23

# Python code to demonstrate example of
# math.fabs() method
# importing math module
import math
# numbers
a = 10      # +ve integer
b = 10.23   # +ve float
c = -10     # -ve integer
d = -10.23  # -ve float
# printing absolute values
print("fabs(a): ", math.fabs(a))
print("fabs(b): ", math.fabs(b))
print("fabs(c): ", math.fabs(c))
print("fabs(d): ", math.fabs(d))

Output

输出量

fabs(a):  10.0
fabs(b):  10.23
fabs(c):  10.0
fabs(d):  10.23
