Template:Log-star/doc
From OeisWiki
The {{log-star}} mathematical formatting template displays a raised text-style low asterisk, since a superscript script-style asterisk is both too high and too small for some mathematical notation, e.g. for the iterated logarithm denoted log ⁎. It also links to iterated logarithm.
Code Result {{log-star}} vs. log{{sup|*}} vs. [[iterated logarithm|log{{sup|*}}]] log ⁎ vs. log - vs. log *
Examples
Examples with valid arguments:
Code Result {{math|{{log-star}}|&}}
log ⁎ {{math|{{log-star|10}}|&}}
log ⁎10 {{math|{{log-star|lg}}|&}}
lg ⁎ {{math|{{log-star|2}}|&}}
log ⁎2 {{math|{{log-star|lb}}|&}}
lb ⁎ {{math|{{log-star|''e''}}|&}}
log ⁎e {{math|{{log-star|ln}}|&}}
ln ⁎ {{math|{{log-star|''a''}}|&}}
log ⁎a
The code
{{math|{{log-star|2}} 65536 {{=}} {{log^*|65536|2}}|&}}
yields
-
log ⁎2 65536 = 4
Examples with invalid arguments:
Code Result {{log-star|-1}} Log-star error: Base (first argument) must be greater than 1 {{log-star|0}} Log-star error: Base (first argument) must be greater than 1 {{log-star|1}} Log-star error: Base (first argument) must be greater than 1
