Your task is to develop a function `is_prime_number`

in Python that checks if a given number is a prime number. The function should return `True`

if the number is prime, and `False`

otherwise.

### Function Requirements

**Name:**`is_prime_number`

**Input:**A single number (can be positive, negative, or a floating point number).**Output:**`True`

if the number is a prime number,`False`

otherwise.

### Examples

`is_prime_number(5)`

should return`True`

, as 5 is a prime number.`is_prime_number(4)`

should return`False`

, as 4 is not a prime number.

### Key Points

- Ensure your function handles a variety of cases, including negative numbers and non-integer values, as they will be part of the challenges.
- Your implementation should efficiently determine the primality of a number.

Good luck, and happy coding!
