Type: Number

The Number type represents a number between -(2⁶³ - 1) and 2⁶³ - 1. Numbers are implemented as double-precision 64-bit binary format IEEE 754 compliant numbers. In addition to the normal range, there are three additional special values: +Infitinty, -Infinity, and Not a Number.

Note that there is no explicit integer type in Waltz. When a parameter expects an integer value, the decimal places of the number are simply ignored, so 1.67 becomes 1.

Constructing

There is no need to explicitly construct a Number, nor is there an explicit constructor. Assigning a literal numeric value is enough to create a Number. It is, however, important to note that there are several different ways to express a literal number:

Method	Literal Expressiosn	Actual Values (in Base 10)
Decimal	123456789 12345.6789	123456789 12345.6789
Octal	0755 0644	493 420
Hexadecimal	0x123456789ABCDEF 0XA	81985529216486900 10
Exponential	1E3 2e6 0.1e2	1000 2000000 10

Permitted Values

A number can be between -(2⁶³ - 1) and 2⁶³ - 1. Keep in mind that the inherent precision of numbers decreases the further from 0 they are until you exceed the normal range, at which point there is not precision and the number has been either +Infinity or -Infinity.

Primitive Bridging

The Number type exists both in Waltz's native context as well as in its Script Expressions. Internally Waltz refers to Numbers as Doubles in reference to their double-precision nature. Numbers are sometimes converted to integers with no decimal places when decimal precision would otherwise make no sense, like when referring to port with a RemoteAddress/IP.
