I don't understand, I think you're using the wrong widget. You want to use
a spinbutton to ask the user to select a value with more than 8 digits.
Spinbuttons are normally used to select a value in a small range. I think
you'd better use a text entry.

You'd better not break the library, other applications who expect a float
might break. Copy the widget source from the GTK library, readjust it to
your needs and rename it to (for example) gtk_spin_button_double. See the
GTK tutorial about adding widgets.
