For example: 0000000000000011.0100000000000000 = 3.25

Note: For a sample PLC program which converts 16 point 16 values to

floating point values, refer to Chapter 4.

The CVIM stores some of the data as a 32 bit integer. The first byte contains

bits 16 through 31 of the integer and the next byte contains bits

0 through 15

of the integer.
