Numeric type definitions
An ‘unsigned integer' is a 32-bit (4 byte) data type that encodes a nonnegative integer in the range [0, 4294967295].
A ‘double' is a 64-bit (8 byte) double-precision data type that encodes a double-precision number using the IEEE 754 double-precision format.
The above definitions are common to both XDR and NDR.
