SE4 Scripting in Python (templatizer again)

Negate: 1. To render ineffective or void; nullify. 2. To deny; contradict; rule out.

Well, I suppose it fits under contradict.

[Fyron]

The negative of a number nullifies it. To negate a number, to nullify it. The null number is 0.

True, but the described operation is 0 - n, where n is the number. The operation you describe is n + (0 - n).

[Kamog]

This works too. How about the operation -1*n where n is the number

Time for a progress report!

The calculator part of the application is coming along great; currently, it can negate, add, subtract, multiply, divide, exponentiate, and take modulos, exponents, percentages, and factorials!

What's left to do:
-Add in variables
-Add in mathematical functions (sin, log, sqrt, and stuff like that)
-Add in user defined functions (if I can - Fyron wants 'em and it shouldn't be TOO hard, just string replacement )
-Add in functions that return strings, not just numbers (if I can - would be useful for generating Roman numerals for components)
-Finally, write the application that parses the SE4 data file templates and generates the actual data files!

Oops, forgot to mention that I needed to add parentheses... Well, I just finished adding those!

BTW, will anyone be needing functions that take multiple parameters? I could easily implement single-parameter functions as unary operators and not write proper functions, and that would save me a bit of time with the parsing of parameters, but if you really want them...

Well, why not. The more - the better
But if it's too time consiming (multiparam functions)...don't bother with it now. Save it for future Versions

I'll see what I can do then

BTW, I just added 4 more operators:

The "to" operator generates random numbers in a specified range, so 1to6 simulates rolling a normal six-sided die.

The "d" operator acts like in many roleplaying games, rolling multiple dice; 3d6 rolls up a number from 3 to 18 with most values in the 8 to 12 range.

Note that these random generators will NOT allow you to generate random damage for weapons in SE4; it will just generate random numbers in the data files. Which might at least be good for a surprise game if you can keep yourself from peeking at the tech tree

The other two are really statistical operators, but I figured I'd throw them in because I'd already done factorials - the "P" operator calculates permutations while the "C" operator calculates combinations, if you happen to know (or care) what those are...

Time for another progress report!

I added variables today - actually, they're really just named constants, as the program can't perform symbolic manipulations on them. (Though I wonder how hard that would be given what I've set up so far... ) I added 3 built-in variables: pi, e, and c (the speed of light). Any more you might want?

I also added the "E" operator, which does scientific notation, e.g. 3E6 means 3 million.

All that's left now is those pesky functions (and those aren't really even crucial, as long as I can do the single-parameter ones as unary operators) and then I can start incorporating the SE4 files into a client program for this app!

[Ed Kolis]

Almost there... these functions are just getting annoying because I have to basically copy and paste my wrapper classes for one standard math library function to the next...
