Constants

Constants are fixed values. Here are a few examples of valid constants.

// This is an integer constant

55

// Here is a floating-point constant

75.2

// Here is a string constant

"This is a test"

// This is an integer constant in hexadecimal (leading 0x)

0x1F

// This is an integer constant in octal (leading 0)

010

String constants can contain special escape sequences to create unique characters. A caret (^) initiates an escape sequence. Here is a list of the escape sequences that are supported.

Escape Character	Meaning
"^a"	Bell (alert)
"^b"	Backspace
"^f"	Form feed
"^n"	New line
"^r"	Carriage return
"^t"	Tab
"^’"	Single quote
"^""	Double quote
"^^"	A single caret character

You can also specify characters by specifying the ASCII value of the character using either of the following two formats.

"^xNN" Specifies an ASCII character where NN are two hexadecimal (base 16) digits.

"^NNN" Specifies an ASCII character where NNN are three octal (base 8) digits.
