No. 11S018) version dated November 1983.  Hardware Required: Hardware
Floating Point of FP-11 Type, not FIS.  Keywords: Mathematical
Abstract: This package provides a Library of the elementary maths
for the DECUS C system.  The functions have the same names,
arguments and functionality as their counter parts in UNIX so that
porting applications programs from UNIX and UNIX compatible
systems is facilitated.  The functions provided are sqrt, log,
log10, exp, pow, sin, cos, tan, cotan, asin, acos, atan, atan2,
sinh, cosh, tanh, fabs, floor, ceil, frexp, ldexp and modf
together with new versions of atof and $$dtoa.  Most of the
algorithms are from Cody and Waite "Software Manual for the
Elementary Functions", Prentice-Hall, which have been designed to
have a high level of accuracy throughout the entire range of their
arguments.  The test programs from that book are included also, as
are a number of patches which fix bugs in the compiler module
CC103 and the runtime modules DOPRINT, DOSCAN, FCLOSE AND IOABUF.
Restrictions: DECUS No. 11S018 needs to be patched to fix some bugs.
A patch kit is
included with this submission.
