Numeric Constants

Numbers can be expressed in different 4 bases in Brass:

Base	Prefix	Postfix	Example
Hexadecimal (16)	`$`	`h`	`$FA` or `9D94h`
Decimal (10)		`d`	`230` or `45d`
Octal (8)	`@`	`o`	`@023` or `777o`
Binary (2)	`%`	`b`	`%01010101` or `1111b`

Labels can hold floating-point values. You must use decimal for this, and the decimal point '.' regardless of OS localisation.

Character or String Constants

There are two types of constant;

Character constants - A single character is surrounded in 'single quotes' - for example, .db '!'. The advantage of this is that characters can be used as expressions (ld a,'?'-3). If you need to specify the ' character itself, you must escape it with a backslash: '\''
String constants - These are simply plain text surrounded with "double quotes" where each character is converted into the ASCII equivalent - for example .db "Brass has simple string support." Again, to use the " inside a string, you must escape it - "Like \"this\"."

There are a number of escape sequences you can use:

Sequence	Meaning
`\n`	Newline
`\r`	Carriage return
`\b`	Backspace
`\t`	Tab
`\f`	Formfeed
`\\`	Backslash
`\'`	Single quote
`\"`	Double quote

Note that when using character constants you should not escape the double quote symbol and when using string quotes you should not escape the single quote symbol.
