SimplIQ drives cannot evaluate numbers with an absolute value greater than 10 20 . For
example, if you enter =12.3e+20 or -13.56e-20, the SimplIQ drive will respond with a
Badly Formatted Number error.
Logical operators yield 0 or 1 as a result.
The results of logical operators are integers.
4.2.2 Mathematical and Logical Operators
Expressions may contain any combination of arithmetic, relational and logical operators.
Precedence levels determine the order in which the expression is evaluated. Within each
precedence level, operators have equal precedence and are evaluated from left to right.
For example, a*b/c is equivalent to (a*b)/c.
The following table lists the mathematical and logical operators used in the SimplIQ drive
language. The table also specifies operator precedence, ordered from highest to lowest
precedence level.
