AS7263 − Detailed Description
4-Byte Floating-Point (FP) Registers
Several 4-byte registers (hex) are shown in the tables. Here is
an example of how the registers are used to represent floating
point data (based on the IEEE 754 standard):

Example of the IEEE 754 Standard
The floating point (FP) value assumed by 32 bit binary32 data
with a biased exponent e (the 8 bit unsigned integer) and a 23
bit fraction is (for the above example).
