Performing arithmetic operations
Performing arithmetic operations, as discussed in the examples in previous sections, is straightforward. Julia provides a complete set of operators to work on.
Binary operators: +, -, *, /, ^, and %. These are just the most used and small subset of the binary operators that are available.
julia> a = 10; b = 20; a + b30
Unary operators: +, and -.
These are the unary plus and unary minus. The former performs the identity operation and the latter maps the values to their additive inverses.
julia> -4-4julia> -(-4)4
There is a special operator ! that can be used with bool types. It is used to perform negation:
julia> !(4>2)false
