5.3. Constants
(1) Numeric constants
Numeric constants are positive or negative numbers. They can be represented in either their ordinary
form or an exponential form. Numeric constants must lie within the range 10** to 10°* (IE —38 to
1.70141 18E + 38), and the maximum number of significant digits is 8. If the value of a constant is out
of the range, the result of operation is not assured.
Ordinary integers and decimal numbers are represented in their normal form as follows.
123
-123.4
+12
The ‘‘+”" sign may be omitted for positive numbers.
Very large or small numbers are represented in the exponential form. In this form, a number is represented
by a number representing the mantissa, E, and a number representing the exponent. Use of ‘E”’ in
the exponential form is shown below.
1.23E+2
This represents 1.23 x 10x 10=123
—1.2E-1
This represents —1.2+10=—0.12
The ‘‘+’’ sign may be omitted for positive numbers. The mantissa must be less than 10 and greater
than —10 and the exponent must be an integer between —38 and +38.
(2) String constants
A string constant is a set of characters enclosed in quotation marks (** ’’). The maximum number
of characters in a string constant depends on the effective line length, but the total maximum number
of characters of string data permitted is 255. Examples of string constants are as follows.
“ABC!
"12345"
“"MZ-800""
Note:
Quotation marks are not required in DATA statements. (See Chapter 6.)
