Numeric
expression
Function:
Transforms
rectangular
coordinates
(x
,
y)
to
polar
coordinates
(r
,
@).
Parameter:
x
coordinate:
Numeric
expression

Explanation:
1)
Transforms
rectangular
coordinates
(&
,y)
to
polar
coordinates
(r
,
@)
using
the
following
relational
expressions.

2)
The
r
coordinate
of
(,
6)
is
given
as
the
output
of
the
function,
and
the
value
of
the
r
coordinate
will
be
assigned
to
variable
X
and
the
value
of
the
6
coordinate
will
be
assigned
to
variable
Y
at
the
same
time.
3)
Calculation
of
the
@
coordinate
will
correspond
to
the
angle
unit
(DEG,
RAD
or
GRA).
The
value
of
8
will
be
given
within
the
following
range.
DEG:

7-4 Numeric Functions
Argument ©
Numeric expression.
FACT
Function:
Obtains the factorial value for a given argument.
Parameter:
Argument: Numeric expression
The
argument
must
take
an
integer
value
with
the
range of (0 < argument < 69).
Explanation:
1) Obtains the factorial value (x!) of the argument x.
2) An error will occur if argument x contains fractions.
3)
As
a
rule,
the
argument
is
enclosed
in
parenthesis
but
the
parenthesis
can
be
omitted
if the
argument
is
a
variable
or
a
numeric
value.
Example:
FACT 1@ &@ (10!)
FACT 69 b& (69!)
