This library of routines is part of a reference implementation for the Dense
|
|
and Banded BLAS routines, along with their Extended and Mixed Precision
|
|
versions, as documented in Chapters 2 and 4 of the new BLAS Standard.
|
|
|
|
EXTENDED PRECISION is only used internally; the input and output arguments
|
|
remain the same as in the existing BLAS. At present, we only allow Single,
|
|
Double, or Extra internal precision. Extra precision is implemented as
|
|
double-double precision (128-bit total, 106-bit significand). The routines
|
|
for the double-double precision basic arithmetic operations +, -, *, / were
|
|
developed by David Bailey.
|
|
|
|
We have designed all our routines assuming that single precision arithmetic
|
|
is actually done in IEEE single precision (32 bits) and that double precision
|
|
arithmetic is actually done in IEEE double precision (64 bits). The routines
|
|
also pass our tests on an Intel machine with 80-bit floating point registers.
|
|
|
|
MIXED PRECISION permits some input/output arguments to be of different types
|
|
(mixing real and complex) or precisions (mixing single and double).
