## Description

The modf() 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.

## Syntax

Following is the syntax for the modf() method

```import math

math.modf( x )
```

Note − This function is not accessible directly, so we need to import the math module and then we need to call this function using the 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 the parts have the same sign as x. The integer part is returned as a float.

## Example

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

```#!/usr/bin/python3
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(119) : ", math.modf(119))
print ("math.modf(math.pi) : ", math.modf(math.pi))
```

## Output

When we run the above program, it produces the following result −

```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)
```
