The standard math module function **`math.modf()`** is used to split fractional and integer parts of argument value `x`, which returns a two-item tuple of `float` type. For the negative value of `x`, a negative sign will appear with both values of output in a [tuple](https://www.educative.io/answers/tuples-in-python).
# 
## Syntax
```java
math.modf(x)
```

## Parameters
The `math.modf()` function accepts only a single value as input.
* `x`: a numeric expression.

## Return value
This method returns a two-item tuple, with fractional and integer parts in it, i.e., _(fractional_part, integer_part)_

## Demo code
In the code snippet below:
* `x= math.pi`: On passing `pi` value _(3.141592...)_ as an argument, it will return a tuple `(0.14159265358979312, 3.0)` containing fractional and integer parts.
* `x= 786.11`: On passing a positive value of `x`, it will return a tuple of positive values.
* `x= -786.69`: On passing a negative value of `x`, it will return a tuple of negative values.

To check the output, execute now.

# include math module
import math
# ---- code is starting here ----
print("math.modf(math.pi) : ", math.modf(math.pi))
print("math.modf(786.11) : ", math.modf(786.11))
print("math.modf(-786.69) : ", math.modf(-786.69))

What is math.modf(x) in Python?

Splits fractional and integer parts of x, returning a tuple. Positive or negative values are preserved.
