IsPrimeNumber Method (NMathF)

In This Topic

Checks whether the specified number is a prime number

Syntax

public static System.bool IsPrimeNumber( 
   System.int num
)

Parameters

num

Remarks

A natural number (i.e. 1, 2, 3, 4, 5, 6, etc.) is a prime number, if it is greater than 1 and has exactly two divisors - 1 and the number itself. This implementation uses the Trial-Division prime number check method, which can be quite slow for large numbers.

Requirements

Target Platforms: Windows 11, Windows 10, Windows 7, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later)
