Integers
An integer is a 32-bit signed value in the range from
-2,147,483,648 to 2,147,483,647. Literal values may be
specified in binary, octal, decimal, or hexadecimal format:
10b // binary for 2
10o // octal for 8
10h or 10x // hexadecimal for 16
10 // decimal for, yep, 10
Hexadecimal numbers which begin with letters, such as
FF00h for exaple, must be preceeded with a leading zero
(0FF00h) so the compiler can distinguish them from identifiers.
The underscore symbol (_) can by used to separate digits
for easier readablility.
5_000_000 // five-million
0110_0100_0101_0100b // 16-bit binary number
Strings
Strings are lines of text spoken by objects or
printed with the print-statement. When a literal string is
encountered in an expression, an integer value is returned
which is its index into the game's string table.
This makes it possible to assign strings to variables.
int s = "I'm saving this string for later."
print(s);
There are a few escape codes allowed in strings, each beginning
with the backslash symbol. Escape codes are case-sensitive.
| Code
| Description
|
\'
| Single-quote
|
\"
| Double-quote
|
\.
| Continues the string at the first non-whitespace character
on the next line. (Otherwise, strings are not allowed to span
multiple lines.)
|
\s
| Space. All adjacent whitespace in a string is reduced to
a single space character. This code is used to force whitespace.
|
\r
| Carriage-return
|
\n
| New-line
|
\t
| Tab
|
\\
| Backslash
|
If two or more literal strings match exactly, they may
share same the index in the string table.

Characters
Literal characters are enclosed in a pair of single-quotes.
They are evaluated as integers, so they are compatible with any
expression.
'A' // letter A
'1' // digit 1
'%' // percent-sign
' ' // space
'\'' // single-quote
Characters allow all the same escape codes as strings.
Floating-point values
Numbers that contain a decimal point, or end with
a decimal point, are taken as floating-point values.
The first character must be a digit, though.
Floating-point values are not compatible with the
the standard AGAST operators, because the operators expect
integer operands, so functions that expect floating-point
values must be used instead.
var a;
a = 0.5; // OK: assignment always works
a = a + 1.0; // Error: 1.0 is floating-point
a = FloatAdd(a, 1); // Error: 1 is an integer
a = FloatAdd(a, 1.0); // OK
a = FloatAdd(a, intToFloat(1)); // OK
