Constants
Integer Constants:
Integer constants are whole numbers between -32768 and 32767,
inclusive. A decimal point indicates a floating point constant and is not allowed in
integer constants. Negative values are produced with the unary negation operator (-).
Floating Point Constants:
A floating point constant is a number that contains a decimal
point and must have a digit or unary negation operator for the first character. Floating
point constants are of two forms: fixed point form and exponential form. Fixed point
constants must have a leading digit and decimal point somewhere within the number.
