----------------------------------- Homer_simpson Sat May 10, 2003 11:59 pm Math formula solver... ----------------------------------- the point of this program is to input a math formula and get the answer... it only works with */+- at the time but i'm working on brackets. ----------------------------------- Catalyst Sun May 11, 2003 12:05 am ----------------------------------- it doesnt work :( the order of operations isnt there it just reads left to right ----------------------------------- Tony Sun May 11, 2003 12:14 am ----------------------------------- ya, thats what I said earlier in my post... first you have to search your operations for any *s and /s... And do them first. Then resort your array and do left to right the way you have it now once only +- are left. let me give you an example 1 + 2 * 3 - 1 the result should be 6, though your program will output 8 now if you search for *s first... 1 + (6) - 1 after calculating 2*3 you store its value in the place of 2. Then you move the rest of your array down one spot to get rid of non existing *3 (since its already calculated). ----------------------------------- Catalyst Sun May 11, 2003 12:14 am ----------------------------------- im gonna try to make something like this ----------------------------------- Homer_simpson Sun May 11, 2003 10:37 am ----------------------------------- well i'm not done but i'll look forward to fixing the operation order... ----------------------------------- Martin Sun May 11, 2003 8:23 pm ----------------------------------- Check out Bugz' sybolic calculator ----------------------------------- Martin Sun May 11, 2003 8:25 pm ----------------------------------- http://www.compsci.ca/bbs/viewtopic.php?t=568 Bugz's probably the smartest person that I know ----------------------------------- Asok Sun May 11, 2003 9:07 pm ----------------------------------- that one doesn't filter the bedmas though ie. 1+2*3 = 7 the program will say 9 ----------------------------------- Homer_simpson Sun May 11, 2003 9:58 pm ----------------------------------- that is a good caclulater but my projects is a totally different thing when i finish it will be able to give you the answer to x = 2x + 3 I dont think that calc can do that.... ----------------------------------- Asok Sun May 11, 2003 10:14 pm ----------------------------------- x = -3 ----------------------------------- Homer_simpson Sun May 11, 2003 10:41 pm ----------------------------------- grrrrr... the calc doesn't give u that..... ----------------------------------- Asok Sun May 11, 2003 10:53 pm ----------------------------------- well for your program you could have a for loop running all possibilities from -1000 to 1000 and an if statement checking to see if it's correct. eventually you'll find the answer. ----------------------------------- Homer_simpson Mon May 12, 2003 12:35 am ----------------------------------- bwahahahaaaaaa...... that's just dumb!!!! what if some1 enters the equation 3x=x-1000000000 ----------------------------------- Asok Mon May 12, 2003 6:42 am ----------------------------------- well like real-life calculators there can be a character limit. ----------------------------------- Homer_simpson Mon May 12, 2003 12:18 pm ----------------------------------- that's true but first of all not all caclulators solve equations and the ones that do dont do it by guessing numbers...
