Re: Strange Logic in Power of arithmetic

Active State 5.8.8 on Win64

line 1: -8
line 2: -1.#IND
line 3: Illegal division by zero at -e line 1
line 4: -2147483645
[download]

Had to do each one line by line as it failed as a script on line 3 otherwise

version 5.6.1 on Solars

line 1: -8
line 2: NaN
line 3: NaN
line 4: NaN
[download]

If I type them in on Windows as perl -e "print -4**1.5;"..., I get

-8
-4
Illegal division by zero at -e line 1
-2147483645
[download]

`Active State 5.8.8 on Win64 line 1: -8 line 2: -1.#IND line 3: Illegal division by zero at -e line 1 line 4: -2147483645` [download] Interesting. Not on darwin: `$ perlbrew exec perl 1152551.pl perl-5.8.8 ========== Power of calculation test line 1: -8 line 2: nan line 3: nan line 4: nan` [download] The way forward always starts with a minimal test.
