i am developing a calculator for iPad . I would like to ask you if there is a way for DDMathParser to calculate absolute values , e.g (2+4*5)/88 should give 1/4 and not 0.25 . Is it possible to have two modes absolute and exact(decimal)? I would also like to ask you if there is a way to calculate first and second degree equations e.g : 2*x+3=5-7*x should give the value of x=... , derivatives and integrations using DDMathParser? I would really appreciate any help. Thank you in advance . Best regards

  • That's not what absolute value is. – Mick MacCallum Nov 22 '13 at 14:35
  • ok, then how should i call this ? Do you have any ideas on how to implement this using DDMathParser? Thank you in advance – user1480179 Nov 22 '13 at 16:10
  • Probably a [fractional value](http://stackoverflow.com/questions/5552537/convert-decimal-to-fraction-in-objective-c), and what you're trying to do with the derivatives and integrals is a tremendously complicated task. There is no build in way to do this with DDMathParser. – Mick MacCallum Nov 22 '13 at 16:13
  • thank you very much. Do you have any idea about latex functions? Is there a possibility that the DDMathParser can calculate them? Thank you in advance – user1480179 Nov 25 '13 at 06:35
