A scarpet app to turn the Minecraft chat into a scientific calculator. For information on how to install a scarpet script, see the official documentation here. As a scarpet script, it requires the Carpet mod to run, avalible here.
Once the script is installed and loaded with the command /script load chatulator, any chat message starting with > will be evaluated by the calculator; it will ignore everything else. Answers with an absolute value less than 0.0001 or greater than 1000000 will be represented in scientific notation, and all answers are rounded to 4 decimal places by default. Type >show to see the exact value. The rounding and scientific notation settings are configurable, see below for details.
!! Warning !! The calculator currently does not have any error checking, and may return incorrect or unpredictable results if invalid syntax is used.
> "Command prompt"; start a chat message with this to tell the app it's an expression to be evaluated. So > 5 + 3 will return 8, and 5 + 3 will do nothing. The answer is printed only to the person who triggered the script, but your expression is still a regular chat message and thus visible to other players.
+ - * / ^: Works as expected. Use with or without surrounding spaces.
(): Work as expected. Implicit multiplication works, but don't try it with a constant (>(pi)(5) works just fine, but >pi(5) will break. However, >5pi also works.)
e and pi: Useful constants, use like numbers.
ans: The last value calculated. Note that the calculator stores the exact value, not necessarily the rounded value shown.
show: Shows the exact stored value of ans, unrounded and in standard notation.
sqrt(x)
abs(x)
round(x): Rounds to the nearest integer
floor(x)
ciel(x)
ln(x)
log(x): Base 10
sin(x): Default for all trig functions is degrees
cos(x)
tan(x)
csc(x)
sec(x)
cot(x)
asin(x)
acos(x)
atan(x)
rad(x): Number of radians in x degrees
deg(x): Number of degrees in x radians
Loading the script will enable the /chatulator command, which has 6 options:
enableScientificNotation <enable>: Enables or disables scientific notation output. <enable> is a boolean value; true will enable and false will disable.
enableRounding <enable>: Same as enableScientificNotation, but for the rounding output.
configScientificNotation <bound> <magnitude>: Sets either the upper or lower limit for activating the scientific notation output, as an order of magnitude. bound is either upper or lower, and magnitude is an integer representing the order of magnitude at which scientific notation will be enabled (e. g. setting the upper limit to 7 will trigger sci. not. for numbers >= 10000000). Default upper limit is 6 and lower limit is -4.
configRounding <digits>: Sets the number of digits to round to for the output. Default is 4; recommended that this not be set any less than the positive value of the lower limit for scientific notation to avoid non-zero results being displayed as zero.
restoreDefaults: Sets all settings to default values.
listSettings: Prints the current active values of all settings. Note that for the boolean toggles, 1 is equivalent to true and 0 is equivalent to false.
Settings are stored after ech change as per-player app data in the /scripts folder of each world. This means that the settings persist across app reloads and server restarts, but are not shared between singleplayer worlds without manually copying the chatulator.data.nbt file. Settings are read from the file on app load, unless no such file exists, in which case the default settings are loaded and stored in a newly-created data file.
