FEATURES
CZ-0124 is a portable scientific calculator for engineers
and students. It performs various calculation instantly.
Below
is a li
st
of
the basic features
of
this calculator.
L
Large
machine capacity: 8 digit s mantissa and 2 digits
exponent wi
th
sign
each.
2.
Simple operation: Algebraic operation
for
arithmetic
functions.
By
a one-Iouch operation the most often
used
functions
can
be
performed.
3. Wide ran
ge
of
use: Trigonometric functions (sin, cos,
tan, sin -
',
COS
" , tan" ), Hyperbolic functions (sinh,
cosh, tanh, sinh-
',
cosh-
',
tanh -'), Logarithmic
functions (Ln, Log,
eX,
lOX),
Conveniona1 functions
(polar
coordinates to rectangu lar coordinates, re-
ctangular to polar, angle
in
radian to
in
degree,
in
degree
to in radian, angle in degree
to
in
degree/minute/second,
in
degree/minute/second to in degree), Other functions
(yx, n!
, x
1
,.JX,
lfX,
l/x)
4. Convenient for statistical analysis:
With
the ~ key the calculat
or
is set
in
statistical calculation mode and ca lculates the arithmetic mean, the
variance and the number
of
data.
5.
Powerful
in
complex
prob
lems: One independent
memory and two
levels
of
parenthesis.
