Class Dlamc1

java.lang.Object
  extended by org.netlib.lapack.Dlamc1

public class Dlamc1
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.
Contact seymour@cs.utk.edu with any questions.

* .. * * Purpose * ======= * * DLAMC1 determines the machine parameters given by BETA, T, RND, and * IEEE1. * * Arguments * ========= * * BETA (output) INTEGER * The base of the machine. * * T (output) INTEGER * The number of ( BETA ) digits in the mantissa. * * RND (output) LOGICAL * Specifies whether proper rounding ( RND = .TRUE. ) or * chopping ( RND = .FALSE. ) occurs in addition. This may not * be a reliable guide to the way in which the machine performs * its arithmetic. * * IEEE1 (output) LOGICAL * Specifies whether rounding appears to be done in the IEEE * 'round to nearest' style. * * Further Details * =============== * * The routine is based on the routine ENVRON by Malcolm and * incorporates suggestions by Gentleman and Marovich. See * * Malcolm M. A. (1972) Algorithms to reveal properties of * floating-point arithmetic. Comms. of the ACM, 15, 949-951. * * Gentleman W. M. and Marovich S. B. (1974) More on algorithms * that reveal properties of floating point arithmetic units. * Comms. of the ACM, 17, 276-277. * * ===================================================================== * * .. Local Scalars ..
