Data type
In signed binary data, the leftmost bit indicates the sign of binary 16-bit data. The value is expressed in
4-digit hexadecimal.
Positive Numbers: A value is positive or 0 if the leftmost bit is 0 (OFF). In 4-digit hexadecimal, this is
expressed as 0000 to 7FFF hex.

This format conforms to IEEE754 standards for single-precision floating-
point data and is used only with instructions that convert or calculate
floating-point data. It can be used to set or monitor from the I/O memory
Edit and Monitor Screen on the CX-Programmer. As such, users do not
need to know this format although they do need to know that the formatting
takes up two words.
