Hi,
I'm using the PARI library and would like to increase the series
precision. I see that there is a prototype of a function called
"setseriesprecision" in the paridecl.h header file under the
/*default.c*/ comment. However, the "default.c" source code file does
not implement the "setseriesprecision" function. (Though it does
implement the "getrealprecision" and "setrealprecision" functions,
both of which I can use in my code.) I'm using pari-2.3.5 (stable).
I would like to increase the series precision so that functions like
tan(x) are more accurate when using the "gtopoly" function to convert
the series to a poly and then the "gsubstr" function to evalute the
poly at specific values. Perhaps the is also another way to do this?
Any help would be appreciated. Thanks!
Mike
