WebOct 19, 2016 · Figure 1: 16-bit half-precision floating point (FP16) representation: 1 sign bit, 5 exponent bits, and 10 mantissa bits. To get an idea of what a difference in precision 16 bits can make, FP16 can represent 1024 values for each power of 2 between 2 -14 and 2 15 (its exponent range). That’s 30,720 values. WebThis webpage is a tool to understand IEEE-754 floating point numbers. This is the format in which almost all CPUs represent non-integer numbers. As this format is using base-2, there can be surprising differences in what numbers can be represented easily in decimal and which numbers can be represented in IEEE-754. As an example, try "0.1".
