The "numeric constant" parameter represents a number consisting mainly of the digits 0-9; other optional elements are a decimal point (.), a minus sign (-) to indicate a negative number, and a plus sign (+) to indicate a positive number (unsigned numbers are assumed to be positive). If a sign is specified, it must precede the digits. Spaces are not allowed in a numeric constant.
Integers, fixed-point numbers and floating point numbers (numbers in exponential notation) are three types of numeric constants. See the following examples:
- Number

- +15.38
- -86.34
- 10,000
- Integer

- n/a
- n/a
- 10000
- Fixed Point

- +15.38
- -86.34
- 10000
- Exponential
- 4.4E+1
- 1.538E+1
