Avoiding rounding in convert.tosingle method

[ponsakthi]

consider ,

object a =1.123456;

float f = convert.ToSingl e(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.

Is that outside the realm of a float/single?
You're starting with a double after all
