Python modf() Function

Python Numbers

---

Description

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

---

Syntax

The following is the syntax for the modf() method:

import math

math.modf( x )

Note:modf() is not directly accessible; you need to import the math module and call the method through a static object.

---

Parameters

• x -- A numeric expression.

---

Return Value

Returns the integer part and fractional part of x.

---

Example

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

#!/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)

The output of the above example after running is:

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)
