CHECK
An
overflow

tion
becomes

(9.999999999
x
1099)
(‘"-E—""
sign
appears).
b)
When
function
calculations
are
performed
with
a
number
exceeding
the
input
range
(—-E-""
sign
appears).
c)
When
an
unreasonable
operation
(such
as
an
at-
tempt

¥
and
on
while
”=0)
is
per-
formed
during
statistical
calculations
(‘"-E—"
sign
appears).
;
d)
When
a
mathematically
illegal
operation
(such
as
division
by

is
within
the
range
of
