(12C) Power of Negative Number
Program to solve for Negative Base with Fractional Power

X^Y can calculate as -X^(Fractional Y)

Procedure:

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:
Code:
 01 0 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 09 0 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

Remark: This program doesnâ€™t calculate in the complex numerical form.
