How many bits in a float

WebJan 5, 2012 · Well, here's a quick explanation: An int and float usually take up "one-word" in memory. Today, with the shift to 64bit systems this may mean that your word is 64 bits, or 8 bytes, allowing the representation of a huge span of numbers. Or, it could still be a 32bit … Single-precision floating-point format (sometimes called FP32 or float32) is a computer number format, usually occupying 32 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 …
