Expression Manipulator v0.6
It's been a long time since the last update, so I figure I'll post this one before doing my next big change.
minor changes:
- bugs fixed in handling functions
- A template class Set was created to unite a set of Variables and a set of Expressions (in theory, anyway)
major changes:
- The console is much better than it was in the beginning. It will keep asking for an equation until you tell it to quit. Some commands:- #quit() -- hmm... wonder what this does...
- #definefunc(function_name,expression of function,parameter1,parameter2,...) -- this defines a function
an example:
Code:
:> #definefunc(h,f(x),x)
:> f(3)
f(3)=f(3)
:> h(3)
f(3)=f(3)
:> h(2)
f(2)=f(2)
:> #definefunc(f,3+x,x)
:> h(2)
5=5
:> _
- #help() -- some hints on using it
- Along with the console change, a history function was added:
ans(# of lines back, parameter number)
ie:
Code:
:> 3=5
3=5
:> ans(0,1)
5
- To speed up typing, some shortcuts were added:
Code:
:> 3 = 5
3=5
:> +3
6=8
:> /x
6*x^-1=8*x^-1
(Subtracting like this isn't supported because it would be confused with the minus sign. Instead, put a plus before it:
ie: +-4x instead of -4x
- Exceptions added and standardized
Most of the older functions are listed in the Documentation file.
The executable might be posted later today, if it fits the size limit here.
