* Logicandcompare (#50)franksl2019-11-261-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * TokenFactory: allowing multicharacter tokens * Added logical and compare operators: <, <=, >, >=, ==, !=, ||, && * Fixed operator priorities * Error messages fixes * Fixed operators priority The priorities are assigned by following the php language standard (https://www.php.net/manual/en/language.operators.precedence.php) I've assigned precedence in steps of 10 units by following the linked page: 230 clone new 220 ** 210 ++ -- ~ (int) (float) (string) (array) (object) (bool) @ 200 instanceof 190 ! 180 * / % 170 + - . 160 << >> 150 < <= > >= 140 == != === !== <> <=> 130 & 120 ^ 110 | 100 && 90 || 80 ?? 70 ? : 60 = += -= *= **= /= .= %= &= |= ^= <<= >>= 50 yield from 40 yield 30 and 20 xor 10 or * Added if() function * Cache key fix There are cases where the cache key creation raised an error, for example while evaluating the expression "if(cos(2), cos(2), 0)", because the if() function was passing a float to the MathExecutor:execute() method.

| |/ | | | | | | Basically the token that is causing the exception for better diagnostics.
* / Support for double quoted stringsBruce Wells2018-09-121-16/+34
|/ | | | | | | | Changed array() to [] syntax. Added variable in question to unknown variable exception. Added getVar and getVars accessor functions. Added getOperators and getFunctions accessor functions for completeness. Extended all Exceptions off MathExecutorException.
* + Added cache, which speeds up the repetitive calculationsNeonXP2013-09-061-1/+25
| | | | + Returned variables, because they need for cached expressions
* Mass refactoringNeonXP2013-09-061-0/+125
Some changes: + Added support of functions with multiple arguments + Added some default function (min, max, avg). just example of multiple arguments :) - Removed variables support (I think they pointless) ~ All tokens now in individual classes ~ Parsing based on regular expressions ~ Fix negative numbers ~ Fix grouping with brackets
