Avoiding rounding in convert.tosingle method

Question

consider ,

object a =1.123456;
float f = convert.ToSingle(a);

But when I print the value of f , I get 1.123455.

It is getting rounded off. Also the problem is I cant change the data type of float in the code. Please help.

This is done because of the way the floating-point type works. If you want a better precision (in the cost of some performance) - use the Double or Decimal type instead.
