log10('-Infinity');
log2('-Infinity');
power('Infinity',2)
As above, using the + infinity function in some math functions will report
an error in arrow-datafusion, but mysql and posgtres will not report an error.
I think the + infinity parameter is meaningful in mathematics.
--postgres
postgres=# select power('Infinity', -2);
