Type

Description

Boolean

True or False.
When casting a Boolean as Integer, by convention True maps to 1, False maps to 0. When casting an Integer as Boolean, 0 maps to False, all other values map to True.

Methods:

• ToString

Float

Double-precision floating point. 15 significant digits, exponent -308 to +308.
Presence of a dot "." differentiates literals from an Integer.

Notations:

• Normal. E.g. 948.4685
• Exponential. E.g. 9484685e23

Methods:

• ToString: conversion to decimal string

Integer

64bit signed integer. From -9223372036854775808 to 9223372036854775807.

Notations:

• Decimal. E.g. 948 ; -65190
• Hexadecimal. E.g. $1AF or 0x1AF
• Binary. E.g. 0b10011101

For formatting purposes, the underscore character "_" is accepted and ignored in Hexadecimal and Binary literals.

Methods:

• ToString: conversion to decimal string

String

Mutable, copy-on-write, 1-based, UTF-16 string. Strings can be delimited by a single or a double-quote.
In a single-quoted string, a single quote can be expressed by doubling it. In a double-quoted string, a double-quote can be expressed by doubling it. Double-quoted strings can span multiple lines.

Explicit Unicode characters can be specified by using # followed by an integer value (decimal or hexadecimal). Characters specified this way are always understood as Unicode value:

Print('Hello'#13#$0D'World');

Will print 'Hello' followed by CR+LF (ASCII code 13 and 10), followed by 'World', it can also be defined with

Print("Hello
World");
