Examples
-
For BlueGene/Q, a quad floating point unit, capable of up to four double-precision floating point operations at a time, has been added to every A2 core.
Ars Technica Peter Bright 2011
-
This architecture supports, on a block-by-block basis, various precisions per block, ranging from low resolution fixed point video up to single-precision floating point within a single DSP block, and even double-precision floating point with minimal external logic.
unknown title 2011
-
Regan speculated that this particular number is troublesome because it is the "largest subnormal double-precision floating-point number."
-
In the Linpack benchmark, the performance is rated at between 1 and 1.4 petaflops (double-precision value), but when faced with vector computer calculations, the performance can be as high as 150 teraflops.
-
Support for additional double-precision floating point routines in OpenCL kernels to enable greater computational accuracy in HPC and scientific based applications.
-
These two Bulldozer quasi-cores have a shared floating-point scheduler and two integer schedulers; if the integer units are doing nothing, this quasi-core can execute four double-precision or eight single-precision floating point operations in a single clock.

-
The prior Altix 4700 machine was rated at 937 gigaflops doing double-precision floating point math - something you can get out of two Nvidia or ATI graphics cards these days.
The Register 2010
-
It uses signed double-precision floats to store Julian Days, a date well-known to astronomers and able to handle dates and times in the full range of recorded history.
-
Recent introductions in the SH-2A series include the SH7216, SH7262, and SH7264, which offer single - and double-precision FPUs.
