%
In ASCII, the character code decimal 37 (or hexadecimal 25) is defined to be % .
The symbol % (pronounced "percent sign") is used in Pascal:
- it indicates a binary numeral expression/number.
The percent sign also appears in Lazarus IDE directives of the form {%directive}
Example
program simple_binary_digit;
var b:byte;
begin
b := %1010011;
writeln (b);
writeln (binStr(b,8));
writeln ;
writeln ('Press [Enter] to finish');
readln;
end.
The output prints as follows:
83 01010011 Press [enter] to finish
