There are 4 precedence categories in mikroPascal PRO for AVR. Operators in the same
category have equal precedence with each other.

Each category has an associativity rule: left-to-right (

 

), or right-to-left (



). In the

absence of parentheses, these rules resolve the grouping of expressions with operators
of equal precedence.

Arithmetic operators are used to perform mathematical computations. They have numer-
ical operands and return numerical results. Since the char operators are technically bytes,
they can be also used as unsigned operands in arithmetic operations.

All arithmetic operators associate from left to right.
