WebJun 16, 2024 · Understand that what you are really trying to do is simply output the bits in memory that make up a float. Which in virtually all x86 type implementations are stored in IEEE-754 Single Precision Floating-Point Format. On x86 that is 32-bits of data. WebIf you really want to bit-shift a float, you could use a method called fixed-point. Say you want to hold the number 1.23 (and bit-shift it later). You would store 123 in an int, and every time you accessed the variable you would divide the value by 100: Code: greensboro police accident reports online
