Sharp MZ-800 - 5.8 Functions

5.8 Functions
(1) Numeric functions
Numerical
functions
such
as
SIN
and
COS
perform
arithmetic
operations
on
given
numeric
expres-
sions
then
return
the
result.
The
MZ-800
is
provided
with
the
following
numerical
functions.
ABS(X) — Absolute value
Returns the absolute value of numeric expression X.
Example: A= ABS(X). When X=2.9, A=2.9; when X= —5.5, A=S.5.
SGN(X) — Sign
Returns
1,
—1,
or
0
according
to
whether numeric
value
X
is
greater
than,
less
than,
or
equal
to
0,
respectively.
Example: A=SGN(X). When X=0.4, A=1; when X= —1.2, A=—1.
INT(X) — Integer
Returns the largest integer which is less than or equal to X.
Example:
A=INT(X).
When
X
=3.87,
A=3;
when
X=0.6,
A=0;
when
X=
—3.87,
A=
-—4,
SQR(X) — Square root
Returns
the
square
root
of
X.
The
value
specified
for
X
must
be
greater
than
or
equal
to
0.
Example: A=SQR(X). When X=4, A=2.
EXP(X) — Exponential
Returns the value of the natural base e to the power of X.
Example: A=EXP(X)
Trigonometric Functions
SIN(X)
Returns the sine of X, where X is an angle in radians.
Use the following expression to obtain the sine of an angle in degrees.
SIN (X * 7/180)
Example: A= SIN(X)
COS(X)
Returns the cosine of X, where X is an angle in radians.
Use the following expression to obtain the cosine of an angle in degrees.
COS (X * #/180)
Example: A =COS (X)
TAN(X)
Returns the tangent of X, where X is an angle in radians.
Use the following expression to obtain the tangent of an angle in degrees.
TAN (X * 7/180)
Example: A= TAN(X)
ATN(X)
Returns
the
arc
tangent
of
X
in
radians.
The
value
returned
is
within
the
range
—2/2
to
x/2.
Use
the
following
expression
to
obtain
the
arc
tangent
of
X
in
degrees.
ATN (X)* 180/x
Example: A= ATN(X)
