A number sign (#) precedes a hexadecimal (hex) value. You can define literal hexadecimal integer, string, character, or binary values.
Hexadecimal strings in JADE are represented as a sequence of space-separated hexadecimal characters.
The following example illustrates the use of string and integer hexadecimal literals in defining a series of constants.
constants WhiteSpace = #"09 0A 0B 0C 0D 20"; MaxInt = #7FFFFFFF; MaxInt16 = #FFFF; BitMask01 = #55555555;
To define a binary hexadecimal literal value, enclose a sequence of space-separated hexadecimal characters in bracket symbols ([]). For example:
DaysInMonth = #[1F 1C 1F 1E 1F 1E 1F 1F 1E 1F 1E 1F];
The following daysInMonth method of the
daysInMonth(isLeapYear: Boolean): Integer; constants //construct a compile-time value array DaysInMonth = #[1F 1C 1F 1E 1F 1E 1F 1F 1E 1F 1E 1F]; begin if self = 2 and isLeapYear then return 29; endif; return DaysInMonth[self]; end;
