C# float to decimal conversion

Question

Any smart way to convert a float like this:

float f = 711989.98f;

into a decimal (or double) without loosing precision?

I've tried:

decimal d = (decimal)f;
decimal d1 = (decimal)(Math.Round(f,2));
decimal d2 = Convert.ToDecimal(f);

Answer 1

have you tried?

decimal.TryParse()

There are no implicit conversions between float/double and decimal. Implicit numeric conversions are always guaranteed to be without loss of precision or magnitude and will not cause an exception.

Answer 2

It's too late, the 8th digit was lost in the compiler. The float type can store only 7 significant digits. You'll have to rewrite the code, assigning to double or decimal will of course solve the problem.

Answer 3

You lost precision the moment you've written 711989.98f.

711989.98 is decimal. With f in the end you are asking the compiler to convert it to float. This conversion cannot be done without loosing precision.

What you probably want is decimal d = 711989.98. This will not loose precision
