Is this function available?

So, there is power function. You can put 2^3 in your equation and you will get 8. Is there something that does the opposite? Something that gives you 2 to what power is 8? Nothing is on the parser page. I need this to make a range penalty figurer macro.

[Phergus]

That would be log base 2. Which I don't believe the parser does.

Easily emulated with a short table. 16 entries would get you to a range of 65536.

[brad]

True. A table will work. Thanks.

I see how to use the table in a Global macro, but is there a way to call a specific value of a table with a Token macro?

[Azhrei]

That would be log base 2. Which I don't believe the parser does.

A logarithm of X to base B can be calculated if any logarithm function is available. The formula is log(X) / log(B), where log() can be base 10 logarithm, or the natural logarithm, or any other. Most function libraries will provide either log() to calculate base 10 logarithms and ln() for natural logarithms.

I added support for the Math function log and ln into the parser. The next version of MapTool will be released with the new parser.

Giliath, I know I for one would love you forever if you were to include some way to have a variable roll expression:

xd6 where x is either a property OR a prompted variable. At this point, something like 4E fighter power Brute Strike has to be done manually in the macro's instead of using a property since in the case in point, the fighter is using a weapon that rolls 2d6 instead of a single dice and this power does 3[W] which translates to 3(2d6) which turns into 6d6 damage.....

Yeah, that would be awesome. It was something I pined for in 3.5 playing a Psion, when one time I might do a 3d6 energy ray, and another time a 6d6, or any number of d6 from 1 to my current level!

[giliath]

You can. 4d6 is just a short form of roll(6, 4), so you can put variables or prompting expressions in that.

Does that solve what you need?

I may have the order of parameters inverted.

Code: Select all

Try roll(4, 6) for 4d6 instead.

[trevor]

You can. 4d6 is just a short form of roll(6, 4), so you can put variables or prompting expressions in that.

Does that solve what you need?

So you could technically do:

attack for [roll(6, AttackCount)]

?

[jfrazierjr]

You can. 4d6 is just a short form of roll(6, 4), so you can put variables or prompting expressions in that.

Does that solve what you need?

That is part of it. part 1 is using a variable expression to say how many of X dice needs to be rolled as you state above. part 2 is how many times to roll expression x:

x[d20+1+2+0] where x is prompted for and the entire expression is rolled x times

d20+1+2+0 => 14+1+2+0 = 17
d20+1+2+0 => 18+1+2+0 = 21
d20+1+2+0 => 7+1+2+0 =10

Also, I just tried the whole roll(x,y) thing inside [] and was told I was a cheater....heh... not exactly what I expected...

hmmmmm ..... unless you _are_ a cheater ...... heh j/k

[giliath]

We don't support that yet. You need looping of some sort which we have been talking about lately, but before that we need more boolean logic.

[Craig]

Just place a space between the opening square bracket and the roll so
[ roll(x,y)]

Thanks giliath, that will be very helpful.
