REAL,32 or SREal selects the binary IEEE standard 754 single precision data format. The figure
below shows the normal byte order format for each data element. For example, if three valid elements
are specified, the data string for each reading conversion is made up of three 32-bit data blocks. Note
that the data string for each reading conversion is preceded by a 2-byte header that is the binary
equivalent of an ASCII # sign and 0.
REAL,64 or DREal selects the binary IEEE754 double precision data format and is shown in the
following figure (normal byte order shown). This format is similar to the single precision format except
that it is 64 bits long.
