C#, Operator '*' cannot be applied to operands of type 'double' and 'decimal'

Question

This error should be a simple one but I cant seem to make it work. The problem lies in the fact that this very same code works earlier in the program. I don\'s see any reaso

Answer 1

You didn't say which line it was, but I'm betting on these two:

z = (x*y)*(.8 * 1.732050808m);

And:

z = (1000 * x)/(y * 1.732050808m)* .8;

Note that your .8 does not have the 'm' qualifier. Every other place I see you did supply that.
