Logical and arithmetic operations in Julia

Logical and arithmetic operations are very similar to in other programming languages. Julia has an exhaustive collection of all the operators required.

Let's start with the most common operators--arithmetic operators.

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 + b
30

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
-4

julia> -(-4)
4

There is a special operator ! that can be used with bool types. It is used to perform negation:

julia> !(4>2)
false

Performing bitwise operations

These are not frequently used, except...
