Fixed-Point Numeric Literals
A numeric literal is a character-string whose characters are selected from the digits 0 through 9, the plus sign, the minus sign, and the decimal point. This implementation allows for numeric literals of 1 to 18 digits in length. The rules for the formation of numeric literals are as follows:
If a literal conforms to the rules for the formation of numeric literals, but is enclosed in quotation marks, it is a nonnumeric literal and is treated as such by your COBOL system.
The size of a numeric literal in standard data format characters is equal to the number of digits specified by the user.
H"nn"where each n is a hexadecimal digit in the set 0-9 A-F; nn can be repeated up to 8 times, but the number of hexadecimal digits must be even.
Floating-Point Numeric Literals
A floating-point literal is written in the form:
If you omit a sign, the system assumes a positive number.
The significand can contain between 1 and 16 digits. A decimal point must be included in the significand.
The exponent is represented by an E followed by an optional sign and one or two digits.
The magnitude of a floating-point literal value must fall between 0.54E-78 and 0.72E+76. For values outside this range, an error message is produced and the value is replaced by 0 or 0.72E+76 respectively. You must not use a floating-point literal when an integer literal is required.
