In ASCII, the character code decimal 36
(or hexadecimal 24
) is defined to be $
(dollar sign).
Pascal
The symbol $
, pronounced “dollar sign”, is used in Pascal to indicate a hexadecimal base.
program dollarSignDemo(input, output, stderr);
var
i: longint;
begin
// '$' as well as '0x' are recognized by readLn
// as hexadecimal base prefixes
readStr('$24', i);
writeLn(i); // will print 36
writeLn(-$24); // will print -36
end.
An optional sign is written in front the base indicator.
other appearances
For FPC and Delphi compilers, the dollar sign appears in compiler directives of the form {$directive}
.
