Pascal 程序题计算：e=1+1/（2!）+1/（3!）+ …… +1/（n!）（1）求到第50项（2）求最后一项小

(1)
var t,e:real;
i,j:integer;
begin
for i:=1 to 50 do
begin
t:=1;
for j:=i downto 1 do
t:=t/j;
e:=e+t;
end;
writeln(e:0:15);
end.
(保留15位小数)
(2)
var e,t:real;
i,k:integer;
begin
repeat
t:=1;
inc(k);
for i:=k downto 1 do
t:=t/i;
e:=e+t;
until t
