ReadDecimal

Reads 16 bytes from the stream and returns them as a Variant Decimal datatype.

 Public Function ReadDecimal ( ) As Variant

Return Values

Remarks

The Decimal datatype is created from 16 bytes with the same layout as used in .NET. The layout is different than that of VB.

VB Decimal layout
bytes 0-1: Variant datatype information
bytes 2: precision
bytes 3: sign (&H80 is negative)
bytes 4-7: the 32 highest bits in the 96bit value
bytes 8-11: the 32 lowest bits in the 96bit value
bytes 12-15: the 32 middle bits in the 96bit value

.NET Decimal layout
bytes 0-3: the 32 lowest bits in the 96bit value
bytes 4-7: the 32 middle bits in the 96bit value
bytes 8-11: the 32 highest bits in the 96bit value
bytes 12-13: unused (zero)
bytes 14: precision
bytes 15: sign (&H80 is negative)

If the sign byte is non-zero, then the Decimal will be set as negative.
