Integer
Represents integer numbers. Integer maps to JavaScript Number object and is therefore internally always represented as a floating-point number. The compiler will strive to keep the Number object with an integer value, though since Number is a double-precision float that value can exceed the 32 bits range and reach up to 54 bits for regular operands (+, -, <, etc.). Due to JavaScript limitations, value will be clamped to 32 bits for bitwise operands.
Integers can be represented in:
Decimal notation: 123, -456
Hexadecimal notation: $1AF or 0x1AF
Binary notation: 0b10011101
For formatting purposes, the underscore '_' character is accepted (and ignored) in Hexadecimal and Binary literals.
