Question for Joe Horn, Dieter, and other

[Csaba Tizedes]

Hi Namir!

When I was Mechanical Engineer student (17 years ago! OMG!!), I wrote short routines on my 32SII for calculating numbers with errors.

For example if I want to calculate what is the error of volume of a cylinder if the diameter is (0.2 +/- 0.01)m and the height is (0.5 +/- 0.015)m I must to know how to calculate (0.2 +/- 0.01)^2×PI÷4×(0.5 +/- 0.015).

Here is my routines: HP32SII Calculation with intervals.pdf, please check it.

The available routines:

• LAST x
• LAST y
• ENTER
• x CHANGE y
• CLx ( == KILL)
• STO
• RCL
• ADD
• SUBSTRACT
• MULTIPLICATE
• DIVIDE
• INVERSE
• POWER
• ROOT OF
• NAT. LOG
• --- and additionally ---
• SINE
• TAN
  

Enjoy!
