MACHARC

 
C procedure for dynamically determining 13 fundamental parameters associated
with floating-point arithmetic. See W.J. Cody, MACHAR: A subroutine to
dynamically determine machine parameters, TOMS 14, December, 1988 for details.
 
Classes  :  R1 . Machine-dependent constants
 
Type     : C software in BLAS collection.
Access   : Some uses prohibited. Portable.
Precision: Single or double.
Note     : Both float and double versions can be extracted from the supplied
           source code with compiler directives
 
Usage    : rmachar (&ibeta, &it, &irnd, &ngrd, &machep, &negep, &iexp,
           &minexp, &maxexp, &e ps, &epsneg, &xmin, &xmax)
