## Python math.modf() method

math.modf() method is a library method of math module, it is used to get the fractional part and integer part of a number. It accepts a number (integer or float) and returns a tuple that contains fractional part and integer part of the number.

Note:

• The integer part of the number also returns in float
• If the number is an integer, the fractional part will be 0.0
• If the number is a negative number, both of the parts will be negative
• If anything is passed except the number, the method returns a type error "TypeError: a float is required"

Syntax of math.modf() method:

```    math.modf(n)
```

Parameter(s): n – an integer or a float number.

Return value: tuple – it returns a tuple that contains fractional part and integer part of the number n.

Example:

```    Input:
a = 10.23

# function call
print(math.modf(a))

Output:
(0.23000000000000043, 10.0)
```

### Python code to demonstrate example of math.modf() method

```# Python code demonstrate example of
# math.modf() method

# importing math module
import math

# numbers
a = 10
b = 10.23
c = -10
d = -10.23

# printing the fractional and integer part
# of the numbers by using math.modf()

print("modf(a): ", math.modf(a))
print("modf(b): ", math.modf(b))
print("modf(c): ", math.modf(c))
print("modf(d): ", math.modf(d))
```

Output

```modf(a):  (0.0, 10.0)
modf(b):  (0.23000000000000043, 10.0)
modf(c):  (-0.0, -10.0)
modf(d):  (-0.23000000000000043, -10.0)
```
