IEEE 754
Binary floating-point specification
IEEE 754 is the technical standard governing how computers represent and calculate floating-point numbers—the format used for decimals and very large or small values.
The standard defines formats like single precision (32-bit) and double precision (64-bit), along with rules for rounding and handling special values like infinity and NaN (not a number).
Most modern processors and programming languages implement IEEE 754, making floating-point behavior consistent across systems.
