Hi Josh,
Thanks for your help but.. i would like to put 0.3 into r and when i run it,
it shows me that r must be a double and not a float. When i change the
float r to double r. The rest of my program shows me alot of errors with
the double r. Are there any way that i can set my r to read a decimal value
without affecting the rest of the program.
Thanks
Andy
