HP HP-32S - The Status of the LAST X Register

The Status of the LAST X Register
The following operations save x in the LAST X register:
+ , -. x. -*-
SQRT, x2
6*, 10*
LN, LOG
yx
1/x
%, %CHG 2 + , 2- RCL+,-,x,^*
x, 9
SIN, COS, TAN
ASIN, ACOS, ATAN
SINH, COSH, TANH ASINH, ACOSH,
ATANH
IP, FP, RND, ABS
y,x-0,r; 0,r-y,x
-HR, -HMS
-DEG, -RAD
Cn.r; Pn.r x!
CMPLX+/-
CMPLX+,-,x,-=-
CMPLX e*. LN,yx, 1/
x CMPLX SIN.COS.T/
*Note that the recall-arithmetic sequence x I RCL \\T] variable stores a different value in the
LAST X register than the sequence xI RCL I variable (T) does. The former stores x in LAST X;
the latter stores the recalled number in LAST X.
