slapy3(3S)

NAME
     SLAPY3 - return sqrt(x**2+y**2+z**2), taking care not to cause
     unnecessary overflow

SYNOPSIS
     REAL FUNCTION SLAPY3( X, Y, Z )

         REAL      X, Y, Z

IMPLEMENTATION
     These routines are part of the SCSL Scientific Library and can be loaded
     using either the -lscs or the -lscs_mp option.  The -lscs_mp option
     directs the linker to use the multi-processor version of the library.

     When linking to SCSL with -lscs or -lscs_mp, the default integer size is
     4 bytes (32 bits). Another version of SCSL is available in which integers
     are 8 bytes (64 bits).  This version allows the user access to larger
     memory sizes and helps when porting legacy Cray codes.  It can be loaded
     by using the -lscs_i8 option or the -lscs_i8_mp option. A program may use
     only one of the two versions; 4-byte integer and 8-byte integer library
     calls cannot be mixed.

PURPOSE
     SLAPY3 returns sqrt(x**2+y**2+z**2), taking care not to cause unnecessary
     overflow.

ARGUMENTS
     X       (input) REAL
             Y       (input) REAL Z       (input) REAL X, Y and Z specify the
             values x, y and z.
