Single Precision: Single Precision is a format proposed by IEEE for representation of floating-point number. 0 ]
Double precision is not required by the standards (except by the optional annex F of C99, covering IEEE 754 arithmetic), but on most systems, the double type corresponds to double precision. Dans l' IEEE 754-2008 norme, le format de base 2 64 bits est officiellement appelé binary64; il a été appelé double dans IEEE 754-1985. 3 0 R
