Calculator Storage Requirements
The HP-46 requires the use of some storage locations when calculating
certain functions:
® The temporary storage locations of the stack are never required
by the calculator, so you can use them at all times.
e Storage locations 1 through 4 also are never required by the
calculator.
® Storage locations 5 through 8 are used by the calculator when
calculating with the >+, mmm > and =B x , keys (see
Statistical Functions, page 27).
® Storage location 9 is used by the calculator to compute trig
functions and polar/rectangular coordinate conversions (see
Trigonometric Operations, page 33 and Coordinate Conversion,
page 37).
You should not store numbers in storage locations which the calculator
requires for particular operations if you are going to use those
operations. |If you know that you are not going to use the functions
described above, you can store numbers freely in all 9 storage locations.
