values by using a floating radix point. Double precision may be chosen when the range or precision of single precision would be insufficient. In the IEEE 754

the 53-bit double precision. This 128-bit quadruple precision is designed for applications needing results in higher than double precision, and as a primary

half-precision can be over an order of magnitude faster than double precision, e.g. 550 PFLOPS for half-precision vs 37 PFLOPS for double precision on one

base-2 double precision and, more recently, base-10 representations. One of the first programming languages to provide single- and double-precision floating-point

use "D" to signify double precision numbers in scientific notation, and newer Fortran compilers use "Q" to signify quadruple precision. The MATLAB programming

precision is not quite the same as a scale-up of the ordinary single- and double-precision formats it is meant to extend. In a few cases the implementation was

implementation of extended precision enabled standard elementary function libraries to be readily developed that normally gave double precision results within one

programming languages, long double refers to a floating-point data type that is often more precise than double precision though the language standard

extended-precision fraction field is wider, and the extended-precision number is stored as two double words (16 bytes): 28 hexadecimal digits of precision is

−3 + the "bias". In single precision, the bias is 127, so in this example the biased exponent is 124; in double precision, the bias is 1023, so the biased
