WebFeb 20, 2024 · What’s the difference? double has 2x more precision than float. float is a 32-bit IEEE 754 single precision Floating Point Number – 1 bit for the sign, 8 bits for the exponent, and 23* for the value. float has 7 decimal digits of precision. double is a 64-bit IEEE 754 double precision Floating Point Number – 1 bit for the sign, 11 bits ... WebMay 16, 2024 · float32 is a 32 bit number – float64 uses 64 bits. That means that float64’s take up twice as much memory – and doing operations on them may be a lot slower in some machine architectures. However, float64’s can represent numbers much more accurately than 32 bit floats. They also allow much larger numbers to be stored.
