Math::Sign Method (Int64)
Visual Studio 2010
Returns a value indicating the sign of a 64-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Int64
A signed number.
Return Value
Type: System::Int32A 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. |
The following example demonstrates how to use the Sign(Int64) method to determine the sign of an Int64 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 ) ) ); } /* This example produces the following results: Test the sign of the following types of values: Byte : 0 is equal to zero. Int16 : -2 is less than zero. Int32 : -3 is less than zero. Int64 : -4 is less than zero. Single : 0 is equal to zero. Double : 6 is greater than zero. Decimal: -7 is less than zero. The following type is not CLS-compliant. SByte : -101 is less than zero. */
