Program to add, subtract, multiply, divide, simplify to lowest term and
convert to mixed fraction.
-------------------------------------------------------------
The program code is from my previous post for the HP-11C and
program is adapted from member who enhance this program further.
His program is on Post: #2
https://www.hpmuseum.org/forum/thread-11400.html
Remark: Post: #3 was mention about very large fractions that
the normal 11C can't give out correct answer but with the
Free42 or DM42 that came with larger decimal precision I
try that problem and very easily gave result fast and accurate answer.
--------------------------------------------------------------
Assign Soft Menu keys as shown below:
[ADD] [SUBT] [MULTI] [DIV] [MIX] [AF]
-------------------------------------------------------------
To run program:
Initilize menu button to [AF] display "Arithmetic Fractions"
-------------------------------------------------------------
Usage:
Calculate a/b [+ – x ÷] c/d
a [ENTER] b [ENTER] c ENTER d
[ADD] => add
[SUBT] => subtract
[MULTI] => multiply
[DIV] => divide
[MIX] => convert to mixed fraction
The result of each operation is in Y (numerator) and X (denominator).
Even after a mixed fraction has been displayed the simple fraction still
is in Y and X. So chain calculations are possible.
-----------------------------------------------------------
Example:
111 [ENTER] 33 [ENTER] 7 [ENTER] 17
[ADD] => "706" 187
[MIX] => "3" "145" 187
Now subtract 1/187
1 [ENTER] 187
[SUBT] => "705" 187
[R/S] => "3" "144" 187
-----------------------------------------------------------
The [MIX] key can be used independently for displaying mixed fractions.
Example:
355 [ENTER] 113
[MIX] => "3" "16" 113.
