How can I write a program that can display a number
in the significant figure specified by user?

Thanks for your help.

     Thus if pi = 3.14159, the statement "writeln (pi:5:0, pi:5:1,
pi:8:3, pi:8:5, pi:8:6)"
will produce :"    3  3.1   3.141 3.141593.141590".  [Note that the 5:0
format may,
in some implementations, include the decimal point ...].

var x:extended;   {or real or double}
       n,d,z:byte;
readln('number?  ',x);
readln('total places?  ',n);
readln('fractional places? ',d);
readln('number of spaces? ',z);
writeln;
writeln('number =',x:n:d);
writeln('* (',z,' spaces in between) * = *',' ':z,'*');
writeln;
