TYPE OF 32-BIT FLOATING POINT DATA (IEEE 754)
The IEEE 754 standard
point numbers.
As already mentioned, since it is a 32-bit data type, its representation occupies two 16-bit holding registers.
To obtain a binary/hexadecimal conversion of a floating point value it is possible to refer to an online converter
at this address:
http://www.h-schmidt.net/FloatConverter/IEEE754.html
Using the last representation the value 2.54 is represented at 32 bits as:
0x4022 8F5C
Since we have 16-bit registers available, the value must be divided into MSW and LSW:
0x4022 (16418 decimal) are the 16 most significant bits (MSW) while 0x8F5C (36700 decimal) are the 16 least
significant bits (LSW).
