[<System.CLSCompliant(false)>]
static member Sign : sbyte -> int

Public Shared Function Sign (value As SByte) As Integer

Parameters

value: SByte

A signed number.

Returns

Int32

A number that indicates the sign of value, as shown in the following table.

Return value	Meaning
-1	`value` is less than zero.
0	`value` is equal to zero.

A number that indicates the sign of value, as shown in the following table.

Return value	Meaning
-1	`value` is less than zero.
0	`value` is equal to zero.
1	`value` is greater than zero.

Examples

The following example demonstrates how to use the Sign(Int16) method to determine the sign of an Int16 value and display it to the console.

// This example demonstrates Math.Sign()
using namespace System;
String^ Test( int compare )
{
   if ( compare == 0 )
      return "equal to";
   else
   if ( compare < 0 )
      return "less than";
   else
      return "greater than";
}

int main()
{
   String^ str = "{0}: {1,3} is {2} zero.";
   String^ nl = Environment::NewLine;
   Byte xByte1 = 0;
   short xShort1 = -2;
   int xInt1 = -3;
   long xLong1 = -4;
   float xSingle1 = 0.0f;
   double xDouble1 = 6.0;
   Decimal xDecimal1 = -7;
   
   // The following type is not CLS-compliant.
   SByte xSbyte1 = -101;
   Console::WriteLine( "{0}Test the sign of the following types of values:", nl );
   Console::WriteLine( str, "Byte   ", xByte1, Test( Math::Sign( xByte1 ) ) );
   Console::WriteLine( str, "Int16  ", xShort1, Test( Math::Sign( xShort1 ) ) );
   Console::WriteLine( str, "Int32  ", xInt1, Test( Math::Sign( xInt1 ) ) );
   Console::WriteLine( str, "Int64  ", xLong1, Test( Math::Sign( xLong1 ) ) );
   Console::WriteLine( str, "Single ", xSingle1, Test( Math::Sign( xSingle1 ) ) );
   Console::WriteLine( str, "Double ", xDouble1, Test( Math::Sign( xDouble1 ) ) );
   Console::WriteLine( str, "Decimal", xDecimal1, Test( Math::Sign( xDecimal1 ) ) );
   
   //
   Console::WriteLine( "{0}The following type is not CLS-compliant.", nl );
   Console::WriteLine( str, "SByte  ", xSbyte1, Test( Math::Sign( xSbyte1 ) ) );
}
