I give you an example:

For N=360，I=0.27 , PV=1020000 , FV=0, in end mode.

Solve PMT should be PMT=-4439.10. But the Model HP37 ,HP38E,HP 38C show result PMT=-235006353.4

This problem only happen in physical emulator Multi clac and Harald board.


Thank you.

Interesting, on my HP38C emulator I get a result of '-4,433.51' which agrees with the result I get on my real HP12C as well as my HP22 and HP12C emulators.

'Swapping' PV and PMT over (which appears to be the cause of the problem) on my real HP12C gives '-234,667,432.8'.

However, these results are not exactly the same as the answers you gave. What model were you using?
