Converting single-precision real number to 16-bit unsigned
binary data
FLT2UINT(P)
These instructions convert the single-precision real number in the device specified by (s) to 16-bit unsigned binary data, and
store the converted data in the device specified by (d). After conversion, the digits after the decimal point of the single-
precision real number, specified with (s), are truncated.
*1 Supported by engineering tool version "1.035M" and later.
