Curious Feature on the HP-37E Financial Calculator

[bshoring]

People familiar with the Spice Series know that the 38 E/C is the high end financial of the series and the 37 E is the low end, non-programmable model.

The 37 E does have a rather unusual function that the 38, 12, 22, and 27 don't have. It's the PRICE function "X / ( 1-Y/100 )." Its purpose is to calculate retail price given the markup as a % (in Y) and the wholesale or purchase cost in X. The manual gives four different ways this function can be used, including conversions from markup based on cost and market based on selling price and vice versa.

I'm curious as to whether this function has shown up on any other financial calculators that I didn't mention above?
