Numeric - Literals:
The numeric literal can be created with the help of digits only. It can have a sign (+ or -) and can also have a decimal point. If no sign is specified the literal then it will be taken as positive. The Negative literals are represented by - sign at the left most ends. If no decimal point is used then the literal is clearly an Integer. If a decimal point is used, it should come in between the digits. The maximum number of digits permitted in a numeric literal is compiler dependent.
Examples:
Valid Numeric Literal Invalid Numeric Literals
.123 ''123'' (valid as nonnumeric literal but
invalid as numeric literal)
12.5 - 23 (there is a blank space between the
