BASIC
Take
the single-precision
variable,
convert it to a
string
with STRS,
then
convert the
resultant string back
into
a
number with
VAL.
That is, use:
VAL (STR$
(single-precision
variable))
For
example, the
following
program:
10 A!
=
1.3
20 A#
=
A!
30
PRINTA#
prints
a
value of:
1.299999952316284
Compare
with this program:
10A!
=
1.3
20A#
=
VAL(STR$(A!))
30
PRINT A#
which
prints
a
value of:
1.3
The
conversion
in line 20
causes the
value in
A! to be
stored
accurately in
double-precision
variable
A#.
Illegal
Conversions
BASIC
cannot
automatically
convert
numeric
values
to string, or
vice versa.
For
example,
the
statements:
A$=
1234
A%
=
"1234"
are
illegal. (Use STRS
and VAL
to
accomplish
such
conversions.)
