| BinaryReader: ReadDecimal |
Reads a decimal value from the current stream and advances the current position of the stream by sixteen bytes.
Public Function ReadDecimal ( ) As Variant
BinaryReader does not restore the file position after an unsuccessful read.
BinaryReader reads this data type in little-endian format.
The decimal type is created from sixteen bytes using the same layout as the .NET decimal type. The layout is different than that of Visual Basic as shown in the following table.
| Framework | Layout |
|---|---|
| Visual Basic |
bytes 0-1: Variant sub-type information (vbDecimal) bytes 2: precision (0 to 28) bytes 3: sign (&H80 is negative) bytes 4-7: high 32 bits in the 96-bit value bytes 8-11: low 32 bits in the 96-bit value bytes 12-15: middle 32 bits in the 96-bit value |
| .NET Framework |
bytes 0-3: low 32 bits in the 96-bit value bytes 4-7: middle 32 bits in the 96-bit value bytes 8-11: high 32 bits in the 96-bit value bytes 12-13: unused (zero) bytes 14: precision (0 to 28) bytes 15: sign (&H80 is negative) |
If the sign byte is non-zero, then the Decimal will be set as negative.
| Exception | Condition |
|---|---|
| EndOfStreamException | The end of the stream is reached. |
| ObjectDisposedException | The stream is closed. |
| IOException | An I/O error occurs. |
| ArgumentOutOfRangeException | The decimal precision is greater than 28. |
