HP SmartCalc 300s - Manual (Page 5)

• Fix: The value you specify (from 0 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 0 to 10) controls
the number of significant digits for displayed
calculation results. Calculation results are rounded
off to the specified digit before being displayed.
Example:! ^7=1.4286x 10 '(Sci5)
1.429xl0'(Sci4)
Norm: Selecting one of the two available settings
(Norml, Norm2) determines the range in which
results will be displayed in non-exponential format.
Outside the specified range, results are displayed
using exponential format.
Norml: ^a^>\x\.\x\^^0'°
Norm2: 10’>I^|,|^I^10'°
Example:! -r200=5x lO'^(Norml)
0.005(Norm2)

Inputting Expressions and
Values
■Inputting a Calculation Expression Using
Standard Format
Your calculator lets you input calculation
expressions just as they are written. Then simply
press the 0 key to execute it. The calculator
automatically judges the calculation priority
sequence for addition, subtraction, multiplication,
----------------------------------- n------------------------------------
and division, functions, and parentheses.
Example:2(5-F4)-2x(-3)=
E]EG 00 a ms '
ruNF
EISHSS
2(5- f 4)-2 x -3
E4
Inputting a General Function
When you input any of the general functions shown
below, it is automatically input with the open
Parenthesis (() character. Next, you need to inpui
the argument and the closing parenthesis ()).
sin(, cos(, tan(, sin'^ (,cos‘^ (,tan ' (, sinh(, cosh(
tanh(, sinh'i (,cosh'i (, tanh ' (, log(, ln(,e^ (,10^ (
V“(,^(, Abs(, Pol(,Rec(, Rnd(
Example: sin 30=
niNEl 0 ^
[sTnl 0 r01 0 0 Sin(30)
0.5
Pressing sin inputs"sin ("
• 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 con omit the multiplication sign (x) in any
of the following cases.
• Before an open parentheses (S):2x(5-i-4), etc.
• Before a general function :
2xsin(30),2x.^(3),etc.
• Before a variable name, constant, or random
number:20x A2 x:ii elc.
Final Closed Parenthesis
You can omit one or more closed parentheses that
come at the end of a calculation, immediately before
the
0 key is pressed. For details, see “Omitting
a Final Closed Parenthesis” .
