Random Number Generation
(Example #14)
: To generate a random number between 0.000 and 0.999.
: To generate a random number between two specified
positive integers. The entry is divided by " , ".
* The value is show in Ex. #14 only a sample, results will differ each time.
Coordinate Conversion
With polar coordinates, you can calculate and display
within -180º < 180º range. (Same as Radian and
Gradient)
After conversion, results will automatically assigned to
memory variables X and Y.
(Example #17)
STATISTICAL CALCULATIONS
[SD] [REG]
To enter the standard deviation mode by pressing
, [SD] indicator lights up. If press , you can
enter the regression mode selection menu. [REG]
indicator will be turned on.
Before starting, be sure to clear the statistic memory by
pressing .
Perform the data input
(Precautions!)
.
• In SD mode, store the displayed data by pressing ,
pressing will input the same data twice.
• In REG mode, store the x-data and y-data in the form
of:
x-data y-data , pressing will input the
same data twice.
• Use for same data multiple entries.
For example in SD mode, the data 20 has 8 times will
press 20 8 .
• Press or key during or after data input can display
the data value (x) and data frequency (Freq). Follow
with the above example, press will display [x1 = 20],
and press will display [Freq1= 8].
• To edit the stored data, input the new value during the
display of that data value (x) after pressing or key,
and then press to confirm the edit. But, if you
press instead of , a new data value will be
stored.
