In [[computing]], '''octuple precision''' is a binary [[floating-point]]-based [[computer number format]] that occupies 32 [[byte]]s (256 [[bit]]s) in computer memory. This 256-[[bit]] octuple precision is for applications requiring results in higher than [[quadruple precision]]. This format is rarely used and very few environments support it.{{According to whom|date=June 2024}}

The range greatly exceeds what is needed to describe all known physical limitations within the [[observable universe]] or precisions better than [[planck units]].
