## Work with non-decimal 32-bit integer values
## Work with non-decimal 64-bit integer values

In addition to working with individual long integers as decimal values, you may want to perform bitwise operations with long integer values, or work with the binary or hexadecimal representations of long integer values. <xref:System.Int64> values are represented in 63 bits, with the sixty-fourth bit used as a sign bit. Positive values are represented by using sign-and-magnitude representation. Negative values are in two's complement representation. This is important to keep in mind when you perform bitwise operations on <xref:System.Int64> values or when you work with individual bits. In order to perform a numeric, Boolean, or comparison operation on any two non-decimal values, both values must use the same representation.
