shortdesc Enhancement of postscript math operators to use with pstricks
longdesc Postscript lacks a lot of basic operators such as tan, acos, asin,
longdesc cosh, sinh, tanh, acosh, asinh, atanh, exp (with e base). cos, sin
longdesc give result in degrees. pst-math provides all those operators in a
longdesc header file pst-math.pro with wrappers pst-math.sty and pst-
longdesc math.tex. In addition, sinc, gauss, gammaln and bessel are
longdesc implemented (only partially for the latter). pst-math is designed
longdesc essentially to work with pst-plot but can be used in whatever PS
longdesc code (such as pstricks SpecialCoor "!", useful to put labels).
longdesc This work is in progress! PS is limited to single precision so
longdesc complex operators like gammaln can give erroneous results.
