math.significand Method (Single)

mathsignificand Method (Single)

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 float significand(
	float number
)

Public Shared Function significand ( 
	number As Single
) As Single

public:
static float significand(
	float number
)

static member significand : 
        number : float32 -> float32

Parameters

number: Type: SystemSingle
A floating-point number.

Return Value

Type: Single
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(Single)(number) * 2^logb(Single)(number). If number is subnormal, it is normalized so that the significand falls in the interval [1, 2).

Examples

C++

Copy
