(hp-15c) RCL Z !?
While looking at Palmer Hanson's Cadillac quadratic solver for the hp-33s and hp-35s, I found an archive article entitled:
Update: 13 digit precision on HP-15c (from Palmer Hanson). This article includes a program listing for the hp-15c which contains RCL Z. I have scanned through the owner's handbook and the advanced functions handbook without finding a way to execute RCL Z on the hp-15c. Does anyone know how I might input RCL Z on an hp-15c? ter |

My mistake. Was interested in hp-15c implementation of Palmer Hanson's trick for increased precision.
Edit: For those of you who are laughing at me--you have good reason: The quadratic equation solver with 13 digit precision is in the Advanced Functions Handbook for the hp-15c; right at the tail end of the book/pdf-file. ter |
