FLT(452) converts the 16-bit signed binary value in S to 32-bit floating-point
data (IEEE754-format) and places the result in R+1 and R. A single 0 is
added after the decimal point in the floating-point result.
R+1
Only values within the range of –32,768 to 32,767 can be specified for S. To
convert signed binary data outside of that range, use FLTL(453).
