Numeric constants
A numeric constant consists of numeric and special characters, with no intervening spaces, that conform to the following rules:
- Integer -- The characters 0 - 9 without intervening spaces comprise a positive integer.
- Decimal -- A decimal point may be placed before, after, or within the numeric characters.
- Sign -- The first character of a number may be a plus or minus sign.
- Scientific notation -- A number may be suffixed by the letter E, an optional plus (default) or minus sign, and an integer.
