Precedence from the pbp3 manual

The following table lists the operators in default hierarchal order. (Parentheses will
override.) Operators with the same precedence level (on the same line in the table
below) will be evaluated in the order (left to right) that they are encountered in the
written expression.
Highest Precedence
( ) (anything enclosed in parentheses)
- (unary)
! or NOT, ABS, COS, DCD, DIV32, NCD, SIN, SQR
<<, >>, ATN, DIG, HYP, MAX, MIN, REV
*, /, **, */, //
+, - (in math), ~
= or ==, <> or !=, <, <=, >, >=
&, |, ^, &/, |/, ^/
AND, OR, XOR, ANDNOT, ORNOT, XORNOT
