Usage notes for INTLIB and Fortran 90 access to it

1 INTLIB The FORTRAN 77 package INTLIB is ACM Transactions on Mathematical Software Algorithm 737 6], and is thus available over NETLIB 3] and 2], either via FTP (ibid.) or over the World Wide Web 1. It consists of standard FORTRAN 77 subroutines and functions for the elementary operations, some of the Fortran standard functions, and certain logical and utility operations. INTLIB achieves portability with simulated directed rounding, although minor modiications to INTLIB allow true directed rounding, where available. Some simpliication of INTLIB would be possible if it were rewritten with Fortran 90 constructs. However, INTLIB is presently directly accessible through Fortran 90, so its ease of use would not be aaected. Some details not appearing below can be found in 4], 6], and in the instructions provided with the FORTRAN 77 source. The goals and design of INTLIB are consistent with the philosophy stated with the original Level-1 BLAS routines 5]. Namely, the routines are meant to be well-documented, generally available, production quality, and totally 1 The address at the time of writing is
