public class Slabad
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.

 *  Purpose
 *  =======
 *
 *  SLABAD takes as input the values computed by SLAMCH for underflow and
 *  overflow, and returns the square root of each of these values if the

 *  log of LARGE is sufficiently large.  This subroutine is intended to
 *  identify machines with a large exponent range, such as the Crays, and
 *  redefine the underflow and overflow limits to be the square roots of

 *  the values computed by SLAMCH.  This subroutine is needed because
 *  SLAMCH does not compensate for poor arithmetic in the upper half of
 *  the exponent range, as is found on a Cray.
 *
 *  Arguments
 *  =========
 *
 *  SMALL   (input/output) REAL
 *          On entry, the underflow threshold as computed by SLAMCH.
 *          On exit, if LOG10(LARGE) is sufficiently large, the square
 *          root of SMALL, otherwise unchanged.
 *
 *  LARGE   (input/output) REAL
 *          On entry, the overflow threshold as computed by SLAMCH.
 *          On exit, if LOG10(LARGE) is sufficiently large, the square
 *          root of LARGE, otherwise unchanged.
