Fixed point arithmetic for TeX with numbers ranging from -999999999999999999.999999999999999999 to +999999999999999999.999999999999999999

USAGE: - LaTeX2e: where the following options are known: nomessages: don't print messages about the functions that are just computed debug: print debug messages (mainly for ) - LaTeX2.09: include lfp.sty in the document preamble, i.e. - TeX: =

@in@ fp.texfp.tex, =.sty tempbfp fortempa:=fp.tex tempatempb @in@ @in@fp

FILES AND THEIR CONTENTS: - readme.fp: this file - fp.sty includes all files - defpattern.sty: only for internal usage - fp-basic.sty: The following macros are public ones to be used in the document: #1#2#3 #1#2#3 #1#2#3 #1#2#3 #1#2 #1#2 #1#2......#1#2......#1#2......#1 ......#1 ......#1......#1 ............- fp-exp.sty: The following macros are public ones to be used in the document: #1#2 #1#2 #1#2#3 #1#2#3 - fp-random.sty The following macros are public ones to be used in the document: =#1 #1 - fp-pas.sty The following macros are public ones to be used in the document: #1#2 - fp-snap.sty: The following macros are public ones to be used in the document: #1#2#3 #1#2#3 #1#2 - fp-trigo.sty: The following macros are public ones to be used in the document: #1#2 #1#2 #1#2#3 #1#2 #1#2 #1#2#3 #1#2 #1#2 #1#2#3 #1#2 #1#2 #1#2#3 - fp-upn.sty: The following macros are public ones to be used in the document: #1#2 upn-expression #2 Known operations are: +,-,*,/,abs,neg,round,trunc,clip,e,exp,ln,pow,root,pi,sin,cos, sincos,tan,cot,tancot,arcsin,arccos,arcsincos, arctan,arccot,arctancot,pop,swap,copy where pop removes the top element swap exchanges the first two elements copy copies the top element Example: The macro call -0.0617 2.5 + 17.5 - 2 1 + * 2 swap / is equivalent to -0.06:= ((17.5 - (17 + 2.5)) * (2 + 1)) / 2 and evaluates to Afterwards the macro call -0.06-0.06 -1 * 0.2 + sin 2 round `the "" is necessary! is equivalent to -0.06:= round_2(sin((-0.06* -1) + 0.2)) and evaluates to

KNOWN BUGS: - does not work with multido.sty/multido.tex Reason: multido uses the same macro names and Recommended Solution: Patch multido.tex, i.e. apply the following substitutions: FPadd -> mdo@FPadd FPsub -> mdo@FPsub
