In computing, octuple precision is a binary floating-point-based computer number format that occupies 32 bytes (256 bits) in computer memory. This 256-bit octuple precision is for applications requiring results in higher than quadruple precision.
The range greatly exceeds what is needed to describe all known physical limitations within the observable universe or precisions better than planck units.
