SGN - Signum (Sign)
SG
N(numeric-expression)
The
signum function gIves you
the
algebraIc
sign
of
the
value
specified
by
the
argument.
The
argument
is
the
value
obtained
when
the numeric-expression is evaluated.
The
normal
rules for
the
evaluation
of
numeric
expressions
are
used here.
The
signum
function gives different values
depending
on the
value
of the
argument.
These
values
are
given here.

SIN
(numeric-expression)
The
sine
function gives you the sine
of
the
argument.
x,
where
x is
an
angle
in
radians.
The
argument
is the
value
obtained
when
the
numeric-expression is
evaluated.
The
normal
rules
for
evaluating
numeric
expressions
are
used here.
If
the
angle
is
in
Llegrees, simply multiply
the
degrees
by
'IT/180 to get
the
equivalent
angle in radians- You
may
use
(4
*ATN(l))/180
or
0.01745329251944
for
'77/180.
