Operator |
Description |
Simple math operations |
+ - * / () |
Addition, subtraction, multiplication, division and grouping characters: + - * / () .
The multiplication sign * is optional: the expression 2sin(3x) is equal 2*sin(3*x).
Brackets are used to group expressions. |
0.5 |
Use dot as separator in decimals:- 0.5 - correct;
- 0,5 - incorrect.
