ConditionedExpression

Expression1 ["?" Expression1 ":" Expression1 ]

If the section exists with a question mark, HiCAD checks whether the expression before the question mark is zero. If it is, the expression after the colon is taken; if it is not, that before the colon is taken.

Expression2 { ("&" | "|") Expression2}

"&" is a logical And, "|" a logical Or.

SimpleExpression [ ( "=" | "<" | ">" | "<=" | ">=" | "<>" ) SimpleExpression ]

The result of the comparison is 1 for true and 0 for false.

[ "+" | "-" | "!" ] Term { ("+" | "-") Term }

"!" is the logical Not. If the term after the "!" is zero, the result is 1, if not, 0

Factor { ( "*" | "/" | "%") Factor }

"%" calculates the integral remainder in a division (modulo).

SimpleFactor ["^"SimpleFactor]

"^" is the potentiation.

Variable | Number | Constant | Function Call | "(" ConditionedExpression ")"

Bracketing can be used to nest formulas as required.

Function "(" [ ConditionedExpression { "," ConditionedExpression } ] ")"

Parameter-free functions are called using empty brackets: f().

"pi"

"sin" | "cos" | "tan" | ... | "aint" | ...

For the precise list of functions, see below.

Letter {LetterOrDigit | "_"}

Variable names must begin with a letter. The maximum length of a variable name determines the valid length of HiCAD macro variables.
