A.1 DATABASE STRUCTURE
The IMP uses a floating point format similar to IEEE, but not Quite. It is as Follows:
¦SEEEEEEE¦MMMMMMMM¦MMMMMMMM¦MMMMMMMM¦
S = sign bit
E = 7 bit exponent – excess 64
M = 24 bit mantissa - no hidden bits.
Note: Where a parameter is stated as being a value, 0,1, 2 and so on, it is stored in
the database in binary code, not ASCII.
