WebMay 6, 2024 · IEEE-754 Format for 32-bit Floating Point Number Figure-1: 2. Figure-1 demands that the input binary data should be a 32-bit number and must align with it. 3. Your numbers are: (1) Higher 16-bit: 100001001001000 ==> 0 100001001001000 (2) Lower 16-bit 1010001111011 ==> 000 1010001111011 4. WebBasically you are trying to cast an array of four 8-bit values which can have any alignment they like (byte alignment) to a 32-bit float value which needs 4-byte alignment. And the two just don't mesh. Instead you need to work the other way around - cast a type that has smaller alignment requirements over the type that has larger requirements.
