CountDigits(Int16)

Returns the number of digits in the current 16-bit signed integer.

Declaration
public static int CountDigits(this short value)
Parameters
Type Name Description
System.Int16 value

The value whose digit count to compute.
Returns
Type Description
System.Int32

The number of digits in value.

DigitalRoot(Int16)

Computes the digital root of this 16-bit integer.

Declaration
public static short DigitalRoot(this short value)
Parameters
Type Name Description
System.Int16 value

The value whose digital root to compute.
Returns
Type Description
System.Int16

The digital root of value.
Remarks

The digital root is defined as the recursive sum of digits until that result is a single digit.

For example, the digital root of 239 is 5: 2 + 3 + 9 = 14, then 1 + 4 = 5.

Declaration
public static bool IsPrime(this short value)
Parameters
Type Name Description
System.Int16 value

The value whose primality to check.
Returns
Type Description
System.Boolean

true if value is prime; otherwise, false.

LowestCommonMultiple(Int16, Int16)

Calculates the lowest common multiple between the current 16-bit signed integer, and another 16-bit signed integer.

Declaration
public static short LowestCommonMultiple(this short value, short other)
Parameters
Type Name Description
System.Int16 value

The first value.
System.Int16 other

The second value.
Returns
Type Description
System.Int16

The lowest common multiple between value and other.

Mod(Int16, Int16)

Performs a modulo operation which supports a negative dividend.

Declaration
public static short Mod(this short dividend, short divisor)
Parameters
Type Name Description
System.Int16 dividend

The dividend.
System.Int16 divisor

The divisor.
Returns
Type Description
System.Int16

The result of dividend mod divisor.
Remarks

The % operator (commonly called the modulo operator) in C# is not defined to be modulo, but is instead remainder. This quirk inherently makes it difficult to use modulo in a negative context, as x % y where x is negative will return a negative value, akin to -(x % y), even if precedence is forced. This method provides a modulo operation which supports negative dividends.

MultiplicativePersistence(Int16)

Returns the multiplicative persistence of a specified value.

Declaration
public static int MultiplicativePersistence(this short value)
Parameters
Type Name Description
System.Int16 value

The value whose multiplicative persistence to calculate.
Returns
Type Description
System.Int32

The multiplicative persistence.
Remarks

Multiplicative persistence is defined as the recursive digital product until that product is a single digit.
