#  What is the `sympy` library?

**`sympy`** is library that is used for symbolic mathematics. 

**`pip`** can be used to install `sympy`. Refer to the following command:

```
pip install sympy
```
##        
## The `isprime` method

The **`isprime`** method is used to determine whether the given number is a prime number or not. This method is intended to be used for integers. Any floating-point numbers (limited precision numbers) will result in `False`. Negative numbers are not considered prime numbers.


# 
#  Syntax


```python
sympy.isprime(n)
```
#       
#  Parameter value

- **`n`**: This is the number that needs to be tested.
##           
## Return value

The `isprime` method returns `True` if the given positive integer is a prime number. Otherwise, it returns `False`.

##         
## Code example

import sympy

num = 19

print("sympy.isprime(%s) = %s" % (num, sympy.isprime(num)))

num = 19.00

print("sympy.isprime(%s) = %s" % (num, sympy.isprime(num)))

num = -3

print("sympy.isprime(%s) = %s" % (num, sympy.isprime(num)))

## Code explanation

- Line 1: We import the `sympy` module.
- Lines 3, 7, and 11:  We define different integer values for `num`.
- Lines 5, 9, and 14:  We check whether `num` is a prime number or not by using the `isprime` method.

The output indicates that the `isprime` method returns `False` for floating-point numbers and negative numbers.
