It would be helpful to use a subject line a little more descriptive than "Subscribe" :)
I have been deleting all email with the "Subscribe" subject line without reading them because I thought they were just people trying to sub to the list. I usually set up filters on lists to auto-delete any email with "Subscribe" or "Unsubscribe", I'm glad I hadn't gotten around to it yet on this list.... dean writes: > /* > I'm wondering where to cut the cake between prolog and pico/pilog > and thought I'd post a quick example to illustrate i.e. > initially I won't have individual values for variables > but a list of possibles and want the pc to pick the right values for me > using a system of (cast in stone) equations as a filter...just two in this > example. > Apparently for this to work I need to be use integers. > In reality the figures have decimal points so pico's fixed pt. maths looks > a good fit. > > Any thoughts re how to approach this in pico/pilog much appreciated. > */ > > > :- use_module(library(clpfd)). > > main :- > Lsales = [100,200,300], > Lcogs = [10,20,30], > Lgross_profit = [160,180,200], > member(Sales,Lsales), > member(Cogs,Lcogs), > member(Gross_profit,Lgross_profit), > > Ltax = [5,10,15], > Lnet_profit = [100,170,300], > member(Tax,Ltax), > member(Net_profit,Lnet_profit), > > Gross_profit #= Sales - Cogs, > Net_profit #= Gross_profit - Tax, > > format("Gross_profit ~w Sales ~w Cogs ~w\n",[Gross_profit,Sales,Cogs]), > format("Net_profit ~w Gross_profit ~w Tax > ~w\n",[Net_profit,Gross_profit,Tax]). > > /* > ?- main. > Gross_profit 180 Sales 200 Cogs 20 > Net_profit 170 Gross_profit 180 Tax 10 > true ; > false. > */ > > > As an aside....re the output of 'Ls...is it possible to remove the double > quotes when printing the symbols or CARs of the resultant list?/ > I read that initially the VAL is the same as the symbol...and it > is....complete with double quotes. > > Thank you in anticipation and best regards > Dean -- Brad Collins +855 010628234 | b...@chenla.la | Cambodia twitter: http://twitter.com/deerpig | github: http://github.com/deerpig -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
