## Numerals

Integer and real constants can be represented in decimal notation as sequences of digits without commas or spaces, and prefixed with the + or - operator to indicate sign. Values default to positive (so that, for example, 67258 is equivalent to +67258) and must be within the range of the largest predefined real or integer type.

Numerals with decimal points or exponents denote reals, while other numerals denote integers. When the character E or e occurs within a real, it means "times ten to the power of". For example, 7E2 means 7 * 10A2, and 12.25e+6 and 12.25e6 both mean 12.25 * 10A6.

The dollar-sign prefix indicates a hexadecimal numeralfor example, \$8F. Hexadecimal numbers without a preceding - unary operator are taken to be positive values. During an assignment, if a hexadecimal value lies outside the range of the receiving type an error is raised, except in the case of the Integer (32bit integer) where a warning is raised. In this case, values exceeding the positive range for Integer are taken to be negative numbers in a manner consistent with 2's complement integer representation.
