WebThe IA-32 is the instruction set architecture (ISA) of Intel’s most successful line of 32-bit processors, and the Intel 64 ISA is its extension into 64-bit processors. (Actually Intel 64 was invented by AMD, who called it x86-64). These notes summarize a few items of interest about these two ISAs. WebThe IEEE 754 standard specifies a binary128 as having: Sign bit: 1 bit Exponent width: 15 bits Significand precision: 113 bits (112 explicitly stored) This gives from 33 to 36 significant decimal digits precision.
