2.5.1Computational Expressions

In the SCOL language, the results of computations on the right side of an equal sign are placed in the register (variable) on the left. Variables and constants may be used in the expressions.

(1) Order of computational priority

The SCOL language uses the same order of priority used by almost all other computer languages. Specifically;

•When there are brackets, operations inside the brackets are done first.

•Otherwise, operations are performed in the order of: 1.

Assignment of negative signs, 2. Exponentiation, 3.

Multiplication and division, 4. Addition and subtraction

•Should the order of priority be otherwise the same, priority is assigned from the left of the expression to the right.

For example:

a = b + c * d / (e - f) - g,
