Some Maths at Roll20?

  Hello guys, I thought I'd post this section for questions involving some of useful mathematics in roll20 and how to use it. I have some questions to begin! 1) How can I call the maximum value of a variable? Ex: My variable is "HP" and I have the current value of "10" and the max value of "20". How can I proceed, to make a macro that call the max value? I know that, if I make @{selected|HP} then I'll call the value "10" but, about the value "20"? How can I proceed? ( In @{selected|HP} the token linked to the character sheet have to be selected. ) 2) How can I make powers at roll20? Ex: How can I do a macro that calculates "2^3=8"? Exist a symbol that represents "^" at roll20 language? More generally , what operations and mathematical functions are available for use in this language offered by roll20 ? ( Other than "Floor" for example. )

1). You use |max: @{selected|HP|max} see (near the end of the section):&nbsp; <a href="https://wiki.roll20.net/Macros#Using_a_Selected_To" rel="nofollow">https://wiki.roll20.net/Macros#Using_a_Selected_To</a>... 2). &nbsp;There are the basic 4: + - / * and some math special functions. I don't think there are power functions, but check the docs.&nbsp; See:&nbsp;<a href="https://wiki.roll20.net/Dice_Reference#Rounding_Rolls_and_Math_Functions" rel="nofollow">https://wiki.roll20.net/Dice_Reference#Rounding_Rolls_and_Math_Functions</a>

I think there is a suggestion for power here: Additional math functions for character sheets and macros .

The Aaron said: 2). &nbsp;There are the basic 4: + - / * and some math special functions. Modulus operator is also available.

I thank you guys! =D
