linmath++ can handle all mathematical functions with real numbers.
Try to type something like:
  • "5+6"
  • "45*7-3*(-7/6)"


  • + : adition
  • - : subtration
  • / : division
  • * : multiplication
  • ^ : power (note: "3²" will lead to one error, use "3^2")
  • % : floating point modulus
  • | : Integer Division
  • ! : Boolean NOT equal
  • = : Boolean equal
  • < : Boolean less than
  • > : Boolean greater than

Other operations

Other operations like trigonometric and exponential functions are defined in the standart plugin package, check out "the documentation folder for more (doc/)



calc++ can handle variables, when you are on a physics class, for example it can be very usefull. Lets take a pratical example:
Suposse you need to calculate the cinetic energy of a car:
E = 1/2*m*v^2

Setting Variables

Ok, imagine that our car weight is 1200 kg and its speed is 40 m/s Set up two variables for this:
  • "def mass: 1200"
  • "def speed: 40"

Using a Variable

Simply type the variable name:
"1/2 * mass * speed ^ 2

Mathematical Functions


libmath++ works with symbols. Similary to variables there are the genSymbols. The difference between symbols and genSymbols is the parameters, or arguments. Lets use the same example of the car's cinetic energy:

Setting the function

use the same keyword, def.
"def cineticEnergy(mass, speed): 1/2*mass*speed^2"

This command cna be read as "Define the symbol cineticEnergy, in function of mass and speed, as the following expresion: 1/2*mass*speed^2"

Using a Function

To use a function is as easy as usinga variable, try out "cineticEnery(1200, 400)"

Unsetting a function

Use "undef symbol_name()" for functions or "undef symbol_name" for variables.

Function names

functions names should always start and end with a letter.
"test1a" is a valid name!
"test1" is not!
only numbers and letters suported... no special characters like "_" or " " (empty space)



What is it?

Some times genSymbols cant do the work. We need more horsepower! If tou are a programmer, you can write a library, kind of a plugin, just check out "doc" folder for more info. If you're not a programmer, just email-me with what you'd like to see in calc++ standart libraries package.

Return types

Library functions can return some value, like genSymbols, or not! You cannot use a function that does not return into one expresion, but don't worry, libmath++ will tell you when you type something wrong.

Syntax Rules

comma (",") is the default argument separator... which can be changed at compile time on math_global.cpp.

External Libraries

Ok... libmath++ can handle "plugins" but we don't know how to tell it to use plugins.. That's for what keyword "import" is for! just type "import full_library_path_without_spaces" and you're ready to rock!
