# IEEE floating point

From Just Solve the File Format Problem

**IEEE floating point**, or **IEEE 754**, is a set of standard binary (meaning *non-text*) formats for binary (meaning *base-2*) and decimal floating point numbers. The IEEE 754 standard also defines rules for processing such numbers.

The 32-bit and 64-bit formats for binary numbers are used in countless file formats.

There are at least two revisions, IEEE 754-1985 and IEEE 754-2008. The standards documents are not freely available, though the interchange formats are well known.
