Revision as of 21:25, 28 August 2022
You are encouraged to solve this task according to the task description, using any language you may know.
Some computer programming languages are not exactly consistent (with other computer programming languages)
when raising zero to the zeroth power: 00
- Task
Show the results of raising zero to the zeroth power.
If your computer language objects to 0**0 or 0^0 at compile time, you may also try something like:
x = 0 y = 0 z = x**y say 'z=' z
Show the result here.
And of course use any symbols or notation that is supported in your computer programming language for exponentiation.
- See also
- The Wiki entry: Zero to the power of zero.
- The Wiki entry: History of differing points of view.
- The MathWorld™ entry: exponent laws.
- Also, in the above MathWorld™ entry, see formula (9): .

Befunge
Befunge-93 doesn't have explicit support for exponentiation, but there are a couple of fingerprint extensions for Befunge-98 which add that functionality. The example below makes use of the FPDP fingerprint (double precision floating point).
Note that the result is potentially dependent on the underlying language of the interpreter, but all those tested so far have returned 1. Interpreters that don't support Befunge-98, or don't support this fingerprint, should just terminate (possibly with a warning).

jq
jq version 1.4 does not have a builtin "power" function. If it were to be defined using the exp and log builtins as 'log * y | exp', then 0 | power(0) would yield null, and therefore a definition that makes a special case of 0^0 should be considered, e.g. along the following lines:
def power(y): y as $y | if $y == 0 then 1 elif . == 0 then 0 else log * $y | exp end;
This definition will however be unsatisfactory for many purposes because it does not maintain precision for integer values of the input (.) and y.
