                      5: ceil.c
                      6: cos.c
                      7: floor.c
                      8: pow.c
                      9: tan.c
                     10: two.c
                     11:                Corrected sources to reflect corrected modf() return value
                     12:                for negative arguments; e.g. for arg -1.9,
                     13:                modf() used to return intpart -2. and fracpart .1,
                     14:                now (correctly) it returns intpart -1. and fracpart -.9.
                     15:                Other minor cosmetic changes.

                     20: tanh.c
                     21:                Added code to return arg unchanged when less that THRESHOLD
                     22:                in absolute value after Promula reported inaccuracy for very
                     23:                small arguments.

                     26: sin.c
                     27:                Another change by cef: below THRESHOLD, sin(x) now uses
                     28:                Taylor's Series, rather than just returning x.

                     32:                Initial version.  Steve modified the existing i8087 NDP
                     33:                routines 10/19-23/92, including conversion of the old .m
                     34:                sources to current assembler format and simplification of
                     35:                many routines by using i80x87 opcodes which were not present
                     36:                in the i8087.  Appears to work, but not heavily tested.
                     37:

                     40:                Added pol.o and j[01n].o, previously missing,
                     41:                using common C sources.

                     48:                Change fdiv/fsub ops in keeping with cef's as change,
                     49:                for Unix compatability.
