Numeric Constants

Numeric constants are any numeric characters, preceded by an optional minus sign to indicate negative numbers, and an optional decimal followed by more numeric characters to indicate floating point values. Numbers come in two types: 1) integers and 2) decimal numbers.

Examples include:

Integer Numbers
10
-2345
0

Positive integer values may also be expressed in binary (base 2), octal (base 8), and hexadecimal (base 16). Precede binary values with 0b (0b1110 = 14), octal with 0o (0o177 = 127), and hexadecimal with 0x (0xff = 255).

Decimal Numbers
-234.567
56.87
0.0123
PI

Very large and small numbers may also be represented in scientific E notation (added in version 0.9.9.46). http://en.wikipedia.org/wiki/Scientific_notation
