Arithmetics

Arithmetic Expressions

In Wyrd, you can do simple calculations using operators:

• + for addition

• - for subtraction

• * for multiplication

• / for division

Num sum        = 123 + 456
Num difference = 321 - 123
Num product    = 123 * 456
Num quotient   = 456 / 123

const sum = 123 + 456;
const difference = 321 - 123;
const product = 123 * 456;
const quotient = 456 / 123;

To Do: Support remainder operator %

Precedence

When there are chained arithmetics operators, there will be evaluation precedence which follows common mathematic rule: multiplications and divisions have higher precedence than additions and subtractions.

Num ex1 = 1 * 2 + 3 + 4
Num ex2 = 1 + 2 * 3 + 4
Num ex3 = 1 + 2 + 3 * 4

const ex1 = 1 * 2 + 3 + 4;
const ex2 = 1 + (2 * 3) + 4;
const ex3 = 1 + 2 + (3 * 4);

Prioritization

You can also use parentheses to override the precedence of the operators.

Num ex1 = 1 * (2 + 3) + 4
Num ex2 = (1 + 2) * (3 + 4)
Num ex3 = (1 + 2 + 3) * 4

const ex1 = 1 * (2 + 3) + 4;
const ex2 = (1 + 2) * (3 + 4);
const ex3 = (1 + 2 + 3) * 4;

The compilation result will mostly be the same as JavaScript code.
