Syntax

public class PascalSyntax

extends DefaultSyntax

Syntax used by parsers for functions and expressions written in PASCAL. This syntax supports the following operators, constants and functions :

• Unary operators : + -
• Binary operators : ^ * / MOD + - >= <= > < = <> AND XOR OR (from the highest to the lowest priority)
• Condition : IF THEN ELSE
• Constants : PI FALSE TRUE
• Functions : LN LOG EXP SQR SQRT COS SIN TAN ACOS ASIN ATAN COSH SINH TANH INT ABS OPP NOT

The literals may be any decimal or integer number. The operator of assignment is = (there's no statement BEGIN END in the syntax), brackets ( ) and the separator of parameters ,.
The parsed identifiers (name of functions and their parameters) may contain letters, digits, or the character _. The first character can't be a digit.
This syntax isn't case sensitive.
