Decimal.op_Explicit Method (Decimal)

Converts a Decimal to an 8-bit signed integer.

This method is not CLS-compliant.  The CLS-compliant alternative is ToInt16.

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

public static explicit operator sbyte (
	decimal value
)
J# supports the use of custom casts, but not the declaration of new ones.
JScript supports the use of custom casts, but not the declaration of new ones.

Parameters

value

A Decimal to convert.

Return Value

An 8-bit signed integer that represents the converted Decimal.

Exception typeCondition

OverflowException

value is less than SByte.MinValue or greater than SByte.MaxValue.

The following code example converts Decimal numbers to SByte values using the explicit Decimal to SByte conversion.

// decimal to sbyte.
