/*
 * This include file defines the basic types
 * used to define the data structures written on E852 data tapes
 * and elsewhere.
 *
 * int8, uint8    -  8 bit wide MSB integers (more commonly known as 'char')
 * int16, uint16  - 16 bit wide MSB integers (usually 'short')
 * int32, uint32  - 32 bit wide MSB integers (usually 'int')
 * int64, uint64  - 64 bit wide MSB integers (on some systems 'long', on others 'long long')
 *
 * float32   - 32 bit wide IEEE-754 floating point numbers (usually C 'float',  FORTRAN 'REAL')
 * float64   - 64 bit wide IEEE-754 floating point numbers (usually C 'double', FORTRAN 'DOUBLE PRECISION')
 * 
 * MSB means "big-endian", like SGI-MIPS, RS6000 and others.
 * LSB means "little-endian", like Intel x86, WindowsNT and others.
 *
 * Read 'man math' for more details on IEEE-754 floating point numbers.
