Returns the absolute value of a 32-bit signed integer.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public:
static int Abs (
	int value
)
public static int Abs (
	int value
)
public static function Abs (
	value : int
) : int

Parameters

value

A number in the range MinValue < valueMaxValue.

Return Value

A 32-bit signed integer, x, such that 0 x MaxValue.

Exception typeCondition

OverflowException

value equals MinValue.
