Need docs for how to use mathjs functions

[maueroats]

Some obscure mathjs functions work great. The call below shows that $6 = 2*18+(-1)*30$.

xgcd(18,30) => xgcd: [6,2,-1]

Others do not. The call below should produce the multiplicative inverse of 2 mod 13, which is 7.

invmod(2,13) => (intermediate value)(intermediate value)(intermediate value) is not a function

I looked at the source and could not determine what makes these different. Just a line or two of documentation (or even a reply here) could save people some effort.

Looks like the invmod function was added in mathjs v10.1.0 and this plugin is still using mathjs v8.1.1. I'm planning on doing some updates this weekend and will try to get mathjs up to a recent version.
