Number format

Integers can be of any length (in terms of characters) and composed of the characters in the range 0-9. Where appropriate, negative values can be given using the '-' character. Floating point numbers can be in the standard format:

• DIGIT.DIGIT : e.g. 10.56
• DIGIT. : e.g. 10.
• .DIGIT : e.g. .56

or in the mantissa-exponent format (e.g. 10.56e-1). If a floating point number is given where only integers are expected (e.g. indexes), the floating point value is truncated to the nearest integer.
