=={{header|Binary Lambda Calculus}}==
 
In lambda calculus, <code>\n. n n</code> is a function mapping a Church numeral n to the Church numeral n^n. The following BLC program computes this for n=0 by using its empty input as a Church numeral (since nil coincides with Church numeral 0), and outputting in unary (i.e as a string of 0^0 1s), as generated from https://github.com/tromp/AIT/blob/master/rosetta/exp00.lam :

Note also that this is the multiplicative identity (which means that it's consistent with <code>1*0</code> representing <code>0^1</code> and with <code>1*0*0</code> representing <code>0^2</code> and with <code>1*0*0*0</code> representing <code>0^3</code> and with <code>1*2*2*2</code> representing <code>2^3</code> and so on. Also, this is the result of finding the product of an empty list:
 
<syntaxhighlight lang="J"> */''
1</syntaxhighlight>
 
(In <code><nowiki>*/''</nowiki></code> we're finding the product of a list which contains no characters. This is, of course, the same as the product of a list which contains no numbers when both lists contain neither. That said, characters are outside the domain of multiplication in J, so if the list had contained any characters the product would have been an error rather than a result.)

{{works with|jq|1.5}}
jq version 1.4 does not have a builtin "power" function. If it were to be defined
'''Also works with gojq and fq'''
using the exp and log builtins as 'log * y | exp', then 0 | power(0) would yield null, and therefore
<pre>
a definition that makes a special case of 0^0 should be considered, e.g.
$ jq -n 'pow(0;0)'
along the following lines:
1
<lang jq>def power(y): y as $y | if $y == 0 then 1 elif . == 0 then 0 else log * $y | exp end;</lang>
</pre>
 
It is also worth noting that in jq, gojq, and fq, `pow(0; infinite)` yields 0.
This definition will however be unsatisfactory for many purposes
because it does not maintain precision for integer values of the input (.) and y.
