when i posted this i started to make a parser already.
i just thought while doing it, that the math expression node allowing a string input as expression during runtime would be nice to have
wow since you seem to be a fan, ill upload mine to dropbox, have a look at it, i dont think its efficient but it does the job. would be nice to hear back from you. (for my genetic algorithm i only have single digit numbers and the only operators are ±*/ so it was quite easy, i had more problems doing the math since it took me a while to realize that find item * in string array does what i expect from a windows search instead of finding the multiply operator index)
only allows single digit numbers, the 4 basic math operators (+,-,/,x), the variable “rechnung” holds the calculation to test.
