SlashCalc - Calculator

SlashCalc allows any basic or advanced calculation, multiple calculations, and anything /script can do.

SlashCalc assigns the result of every calculation you make to a table. Access these calculations using $n where n is the index of that calculation (you'll see it when you do a calculation)

Examples

• /calc 10 + 5
• /calc $1 / 2
• /calc math.cos(math.pi / 4)
• /calc 1.718 ^ math.pi
• /calc (2.5 - $1) * $0
• /calc math.sin(2.13), math.cos(2.13), math.tan(2.13), 23 % 3

Usage

• SlashCalc uses Lua to execute the expression you enter. Any valid Lua is allowed. (Your input is turned into a function "/calc xyz" is equivalent to "return xyz;" with the exception of "$n" which is a shortcut to previous results.)
• SlashCalc assigns each result to a list. The list is not saved from session to session. To access these type "$number" into your expression.
• "$0" represents your last entry.
• "$1" is the result of the first calculation you made. "$2" is the second... etc.
• Separate multiple expressions with a comma to do multiple calculations on a single line. You will see the result of each expression.
• NEW: You can omit the leading "$0" if you start your input with the binary operators +, *, :, %, or /. (Note, "-" is not included. To start your expression with a minus, either type /calc $0 - XYZ or /calc + -(XYZ). This is because "-" is also a unary operator and starts a negative number literal.)

Expression Syntax

• Any Lua expression is valid syntax.
• Operators: binary + (addition), - (subtraction), * (multiplication), / (division), % (modulo), and ^ (exponentiation); and unary - (negation)
• Note: using "$n" where n is any positive number will substitute the result of that previous calculation, and "$0" is a shortcut for the most recent result. There is no way to escape this behavior at this moment in time.

Mathematical Functions

(From Lua reference manual)

       math.abs     math.acos    math.asin    math.atan    math.atan2
       math.ceil    math.cos     math.deg     math.exp     math.floor
       math.log     math.log10   math.max     math.min     math.mod
       math.pow     math.rad     math.sin     math.sqrt    math.tan
       math.frexp   math.ldexp   math.random  math.randomseed
       math.sinh    math.cosh    math.tanh

These functions can all be called from /calc. All trigonometric functions use radians.
