The calculator can perform many basic and scientific
calculations and additionally can be used to derive units from
previous entries. for example, kilometers per hour is derived from
length and time.
UnitMaster is an RPN calculator. To learn more about the advantages of Reverse Polish Notation, visit: http://h20331.www2.hp.com/hpsub/us/en/rpn-calculator.html.
The following short examples show how to perform calculations with
an RPN calculator.
To calculate 4+3 do the following:
To calculate (4*5)/(8*2):
The following example shows how to derive kilometers per hour.
To create an entry for this value as a unit, Enter a name in the expression
field e. g. Kilometer Per Hour. This field will initially
contain the expression from the
last calculation.
Note that this expression is in post fix
notation.
This value can be over written. Otherwise, the
existing value will be the name of the new unit.
Next, enter the
name of the category in which this entry belongs. If a category with
the entered name all ready exists, it will auto complete. Else, a new
category by that name will be created.
When performing calculations involving units, Unit master is able to
perform dimensional analysis on the entered equation. For
example, 0.5[Acceleration][Time]^2 = [Length].
When the bitwise check box is selected, all values are displayed in hexadecimal format. If input is preceded by 0x or 0X, it is interpreted as hexadecimal. Otherwise it is interpreted as decimal and converted to hexadecimal.
If the Float radio button is selected, Values are displayed in 64 bit IEEE754 floating point format.
Many of the calculator functions have keyboard equivalents.
