Logicandcompare ( #50 )
...
* 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.
