Decimal::ToOACurrency Method (Decimal)
.NET Framework (current version)
Converts the specified Decimal value to the equivalent OLE Automation Currency value, which is contained in a 64-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System::Decimal
The decimal number to convert.
Return Value
Type: System::Int64A 64-bit signed integer that contains the OLE Automation equivalent of value.
The following code example uses the ToOACurrency method to convert Decimal numbers to the equivalent OLE Automation Currency values that are contained in Int64 fields.
