hi
in calculation, my problem needs at least 20 to 30 digits after decimal point for e.g (1.234567898745612321654645454875) for perfect answer. but in matlab using "format long" i just get 15 digits after decimal. is there any way to get values upto 20 to 30 digits after decimal point. kindly help me i will be highly thankful to you
With best Regards Mudasir

No there is not. You will need to use the symbolic toolbox or one of John D'errico Variable Precision toolbox contributions to the File Exchange.
