Operator |
Description |
The simplest mathematical operations |
+ - * / () |
Addition, subtraction, multiplication, division, and grouping symbols: + - * / () .
Multiplication sign * - is optional: expression 2sin(3x) is equivalent to 2*sin(3*x).
Brackets are used to group expressions. |
0.5 |
Decimals are written with a dot:- 0.5 - is correct;
- 0,5 - is incorrect.
