Exponentiation
The
symbol
[
denotes
exponentiation . It
converts both its
operands to
single-precision, and
returns
a
single-precision result.
Note: To
enter the
[
operator, press
(£j
.
For example:
PRINT6[.3
prints
6
to the .3 power.
String
Operator
BASIC
has
a
string
operator
(
+
) which allows you to concatenate (link) two
strings into
one. This operator should be used as part of
a
string expression. The
operands
are both strings and the resulting value is one piece of string data.
The
+ operator links the string on
the right of the
sign
to the string on the
left. For example:
PRINT
"CATS" + "LOVE"
+ "MICE"
prints:
CATSLOVEMICE
Since BASIC does not allow one string to be longer than
255
characters, you will
get
an error if your resulting string is too long
.
Relational Operators
Relational
operators compare two numerical or two string expressions to form
a
relational
expression. This expression reports whether the comparison
you
set up
in your program is
true
or
false. It
will return a
-1
if the
relation is
true;
a
if
it
is false.
