| Floating-point ($ty[float]) constants can be entered in two formats. The first is by just writing the number with its sign, the decimal point (mandatory for the constant to actually be a float and not an integer), and the decimals. For example, ''3.7'' or ''-5.4164'' are valid float constants. Neither the part to the left of the point nor the part to the right of the point are mandatory (e.g. ''37.'' or ''-.25'' are valid), but a point without any digits around it is not a valid floating-point constant. | Floating-point ($ty[float]) constants can be entered in two formats.
