Description
real is the type identifier for a built-in type whose values are 64 bit real numbers.
Example
For example the rather pointless program below uses the real type to repeatedly divide a number into thirds.
program thirds(output);
const
initial = 37.6;
lowest= 0.05;
var
value : real;
begin
value := initial;
repeat
writeln(value, value:12:3);
value := value / 3
until value < lowest
end.Portability
