│ Nota is currently supported on the UNIX systems. It works great │

Normal Numbers │ Numbers in Nota can be in the normal form. │
│ Integer form like 0 or 42480. And in the decimal │
│ form like 1.8402 or 0.5 but remember decimal only │
│ numbers cannot be without zero: so 0.5 is │
│ possible but .5 is not. │

Hex Number │ Hexadecimal Numbers are supported and must be │
│ started with the 0x sign. So 0xfff is a number as │
│ well as 0x123. │

Names │ Nota approaches identifiers much differently than │
│ any other language. In Nota identifiers can have │
│ space within them, so no more camelCase, │
│ PascalCase, –kebab-case, what_ever; You can │
│ simply write things like size of the planet and │
│ it works. │
│ │
│ Also to make it more interesting, Nota even gives │
│ you ‘ (apostrophe) and therefore you can have │
│ things like radius of earth or earth’s radius. │
│ │
│ Numbers are also allowed (but not for the first │
│ letter). You can have names like: X5 or X 5 and │
│ etc. │

Binary Operator │ Binary operators in Nota are: +, -, *, /, ^, %, │
│ ?, and !. They are fully explained in the Binary │
│ Operators section of the Language Reference. │

Negation │ The only unary operator that Nota defines is the │
│ value negation – operator. E.g: -13 + -sin[x]. │

Parentheses │ Nota provides the parenthesis notation to reorder │
│ precedence like: (1 + 2) * 3. │

Parentheses │ Functions in Nota are written not with │
│ parenthesis but with brackets (Sin[x], Log[2, │
│ 100], …). │
│ │
│ Just like identifiers they are case insensitive │
│ so it doesn’t matter how you write them: log[x] = │
