math.significand Method (Double)

mathsignificand Method (Double)

Gets the significand of the specified floating-point number.

Namespace: C
Assembly: C.math (in C.math.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

public static double significand(
	double number
)

Public Shared Function significand ( 
	number As Double
) As Double

public:
static double significand(
	double number
)

static member significand : 
        number : float -> float

Parameters

number: Type: SystemDouble
A floating-point number.

Return Value

Type: Double
The significand of the specified floating-point number, or number if it not normal or subnormal.

Remarks

The significand is a number in the interval [1, 2) so that number = significand(number) * 2^logb(number). If number is subnormal, it is normalized so that the significand falls in the interval [1, 2).

Examples

C++
