Program to solve for Negative Base with Fractional Power
X^Y can calculate as -X^(Fractional Y)
Procedure:
X [R/S] Y [R/S] answer
Example: -55^(1/5)
55 [CHS] [R/S] display 55
5 [1/x] [R/S] display -2.2288
Example: 2^(-1/2)
2 [R/S] dispaly 2
2 [CHS] [1/x] dispaly -0.5 [R/S] 0.7071
Program:
Remark: This program doesn’t calculate in the complex numerical form.

02 X<>Y
03 X<=Y // Is Base Negative?
04 GTO 09 // Base is Negative goto line 09
05 ENTER // Base not Negative
06 R/S // Stop to enter the power
07 Y^X // Calculate normally
08 GTO 00 // Done

10 X<>Y
11 X<=Y // Convert negative integer to positive integer
12 CHS
13 STO 0 // store positive Base
14 R/S
15 STO 1 // store Power
16 FRAC
17 X=0 // Is the Power in Fraction?
18 GTO 20 // No fraction Power
19 GTO 24 // Yes it is fraction Power
20 RCL 0
21 RCL 1
22 Y^X // Power integer calculate normally
23 GTO 00
24 RCL 0
25 RCL 1
26 Y^X // Fractional integer
27 CHS // Change Sign
28 GTO 00
