The best overloaded method match has some invalid arguments for a class constructor (C#)

I'm getting this error and not entirely sure why. In one class I create an object with the following line of code:

StoreSale sale = new StoreSale(1, 13.99);

The constructor inside the StoreSale class looks like this:

public StoreSale(int quantity, float value)
{
   this.quantity = quantity;
   this.value = value;
}

...and I'm getting the error 'The best overloaded method match for 'applicationname'.StoreSale.StoreSale(int, float) has some invalid arguments.'

Could anybody advise me as to what I'm doing wrong?

You get this error because the literal 13.99 is a double, and there is no implicit conversion from double to float. Use 13.99F instead.

StoreSale sale = new StoreSale(1, 13.99F);

13.99 is a double literal. Append an f to make it a float: 13.99f.

In any case, you probably don't want to use binary floating-point for monetary values anyway. decimal is a far saner choice.

13.99 is a double. To make it a float literal add an f: 13.99f.
