Summary description: Enhancement of postscript math operators to use
with pstricks
License type: lppl
Announcement text given by the package's contributor:
- - ----------------------------------------------------------------------
Postscript lacks a lot of basic operators such as tan, acos, asin, cosh,
sinh, tanh, acosh, asinh, atanh, exp (with e base). Also, cos and sin
give result in degrees.
pst-math provides all those operators in a header file pst-math.pro with
wrappers pst-math.sty and pst-math.tex.
In addition, sinc, gauss, gammaln and bessel are implemented (only
partially for the latter). pst-math is designed essentially to work
with pst-plot but can be used in whatever PS code (such as pstricks
SpecialCoor "!", useful to put labels).
This work is in progress! PS is limited to single precision so complex
operators like gammaln can give erroneous results. Any help on
implementing double precision math in PS would be highly appreciated :-)
