Hi,
I’m currently working on MATH-1359
<https://issues.apache.org/jira/browse/MATH-1358?jql=project%20=%20MATH%20AND%20assignee%20=%20currentUser()%20AND%20resolution%20=%20Unresolved>
which is working an analog of the relationship between sin(x) and
sinx(x) = sin(x)/x but instead for log(1+x) = log1p(x). The sine
function has the term "cardinal" associated with it when we actually
perform
cardinal sine (x) = sinc(x) = sin(x)/x
however, I don't seem to see any clearly defined analog, in a quick
glance at the literature , for the log function. Do you have any
thoughts on what the name should be? Clearly first intuition would be
log1pc(x),
but that only follows from the
sinc(x)
naming convention and isn't necessarily rooted in the literature.
Another thought that occurred to me was to name such a function
log1pMultInv(x)
implying that we're also multiplying by the multiplicative inverse.
But, that is not rooted in the literature either. I would love to
hear
any suggestions that folks have for a naming convention that is
intuitive here .
Since there is no standard (and perhaps not much use outside of CM),
I'd suggest to spell it out in full: i.e.
Log1pMultiplyInverse
[Classes "Inverse" and "Multiply" are defined in the package
"o.a.c.m.analysis.function".]

Gilles
Many thanks and all the best,
