Mathematical Calculation Using console application in c#

Question

hi..
I have Console application.I want to do complex mathematical calculation in that.
In my application there is int & double both type of variables.

I want to solve something like..
y=a*x+b*x^2+c*sqrt(x)-d*x^3-e+log(f)*x
some variables are int or some are double.

Thanks

hi.. YesIt will resolve my problem. thanks..

hi Is it resolve you problem? keep in mind if you multiple int and double number than result is always int. hope this will help you.

hi.. YesI have use * instead of Math.bigmul() Thanks...

Jignesh Trivedi · Answer

hi yes bigmul function use to multiple two int number and get the output in long. in this case you can use * operator to multiple double value and int value. int a = 5; double b=10.5; double result = (double)a*b; hope this will help.

Thanks..... I have use Math.bigmul() but this method only allows int variable & i want to do multiplication of int & double.. I have solve problem..Thanks For giving me reply.

hi there is many inbuilt math formula and operator supported by c# ( System.Math) but if you multiple int and double number than result is always int. in this case you have convert you varible to double. y=(a*x) + b*Math.Pow(x 2) + c*Math.sqrt(x)- d*x^3-e+ // we may use Math.Exp Math.Log10(f)*x please refer http://msdn.microsoft.com/en-us/library/system.math.aspx http://msdn.microsoft.com/en-us/library/6a71f45d.aspx
