Inputting Expressions And Values - HP SmartCalc 300s User Manual

* Fix: The value you specify (from О to 9) controls
the number of decimal places for displayed
calculation results. Calculation results are rounded
off to the specified digit before being displayed.
Example:100+7=14.286(Fix3)
14.29 (Fix2)
Sci: The value you specify (from О to 10) controls
the number of significant digits for displayed
calculation results. Calculation results are rounded
off to the specified digit before being displayed.
Ехатріе:1--7-1.4286х107(5сі5)
1.429x 10" (Sci4)
Norm: Selecting one of the two available settings
(Norm1, Norm2) determines the range in which
results will be displayed in non-exponential formot.
Outside the specified range, results are displayed
using exponential format .
Norm1: 10?2|x]. |x| 10°
Norm2: 10% 1х1, 1х12=1019
Ехатр!е:1 +200=5 x 10 ?(Norm1)
0.005(Norm2)

Inputting Expressions and
Values
Bilnputting a Calculation Expression Using
Standard Format
Your calculator lets you input calculation
expressions just as they are written. Then simply
press the [=] key to execute it. The calculator
automatically judges the calculation priority
sequence for addition, subtraction, multiplication,
and division, functions, and parentheses.
Example:2(5+4)-2 х (-3)=
LINE
2020590200 mora"
sg |2(534):2х ET
Inputting a General Function
When you input any of the general functions shown
below, itis automatically input with the open
Parenthesis (() character. Next, you need to input
the argument and the closing parenthesis ()).
sin(, cos(, tan(, sin" (,cos' (Ист! (, sinh(, cosh(
tanh(, sinh"! (,cosh? (, tanh"! (, log(, In(,e^ (10^ (
(Г (, Abs(, Pol(,Rec(, Rnd(
Example: sin 30=
0.5
Pressing inputs"sin С",
* Note that the input procedure is different if you
want to use Math format. For more information, see
"Inputting with Math Format" .
Omitting the Multiplication Sign
You can omit the multiplication sign (x) in any
of the following cases.
* Before an open parentheses ((()):2 x (5-4) , etc.
+ Before a general function :
2x sin (30), 2x 4^ (3), etc.
«Before a variable name, constant, or random
number: 20x A,2 x л elc.
Final Closed Parenthesis
You can omit one or more closed parentheses that
come at the end of a calculation, immediately before
the [=] key is pressed. For details, see "Omitting
a Final Closed Parenthesis" .
