Python3 modf() Function

Python3 数字Python3 Numbers

Description

The modf() method returns the integer part and the fractional part of x. Both parts carry the same sign as x, and the integer part is represented as a float.

Syntax

The syntax of the modf() method is as follows:

import math

math.modf( x )

Note:modf() cannot be accessed directly. You need to import the math module and call this method via a static object.

Parameters

  • x -- A numeric expression.

Return Value

Returns the integer part and the fractional part of x.

Example

The following example demonstrates the use of the modf() method:

Example

#!/usr/bin/python3
import math   # Import the math module

print ("math.modf(100.12) : ", math.modf(100.12))
print ("math.modf(100.72) : ", math.modf(100.72))
print ("math.modf(119) : ", math.modf(119))
print ("math.modf(math.pi) : ", math.modf(math.pi))

After running the above example, the output is:

math.modf(100.12) :  (0.12000000000000455, 100.0)
math.modf(100.72) :  (0.7199999999999989, 100.0)
math.modf(119) :  (0.0, 119.0)
math.modf(math.pi) :  (0.14159265358979312, 3.0)
