BigInteger Explicit Conversion (Decimal to BigInteger)
Assemblies: System.Runtime.Numerics (in System.Runtime.Numerics.dll)
System.Numerics (in System.Numerics.dll)
Any fractional part of the value parameter is truncated before conversion.
The overloads of the method define the types to which or from which a BigInteger object can be converted. Because the conversion from Decimal to BigInteger can involve truncating any fractional part of value, language compilers do not perform this conversion automatically. Instead, they perform the conversion only if a casting operator (in C#) or a conversion function (such as CType in Visual Basic) is used. Otherwise, they display a compiler error.
The following example converts the individual elements in an array of Decimal values to BigInteger objects, and then displays the result of each conversion. Note that any fractional part of a Decimal value is truncated during the conversion.
