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 … Web1 byte: short: 2 bytes: int: 4 bytes: long: 8 bytes: float: 4 bytes: double: 8 bytes: long double: 16 bytes .
