Description

The method modf() returns the fractional and integer parts of x in a two-item tuple. Both parts have the same sign as x. The integer part is returned as a float.

Syntax

Following is the syntax for modf() method −

import math

math.modf( x )

Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.

Parameters

• x − This is a numeric expression.

Return Value

This method returns the fractional and integer parts of x in a two-item tuple. Both parts have the same sign as x. The integer part is returned as a float.

Example

The following example shows the usage of modf() method.

Live Demo

#!/usr/bin/python
import math   # This will import math module

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

When we run above program, it produces following result −

math.modf(100.12) :  (0.12000000000000455, 100.0)
math.modf(100.72) :  (0.71999999999999886, 100.0)
math.modf(119L) :    (0.0, 119.0)
math.modf(math.pi) :  (0.14159265358979312, 3.0)
