    Basic Math
Operator Function Example
+ Addition 4 + 5 (=9)
- Subtraction 9 - 4 (=5)
* Mutiplication 4 * 5 (=20)
/ Division 20 / 4 (=5)
% Modulo( to get the remainder after division) 10 % 3 (=1),
10 % 2 (=0)
^ Raise to a power of 3 ^ 2 (=32=9)

3^3 (=33=27)

 


    Reserved Functions
Operator Function Example
sqrt Square root sqrt(9) (=3)
curt Cube root curt(27) (=3)
sum Summation of an integer ( only the integer part will be considered if the number is not an integer) sum(99) (=1+2+3+...+98+99)
! Factorial for an integer ( if the number is not an integer, only the integer part will be considered)
9! (=1*2*3*4*...*8*9)
exp Exponential function
exp(3) (=e^3)
ln Logarithm base e
ln(23)
lg Logarithm base 10
lg(1000) (=3)
sin, cos, tan Trigonometric functions (argument in radians)
sin(pi/2), cos(pi/2)

(pi=3.1415926535...)
arcsin, arccos, arctan Inverse trigonometric functions arcsin(1)
arccos(0.5)
