Display relative hotness with two decimal digits after the decimal point

I've seen cases where tiny inlined functions have such a high execution count
that most everything would show up with a relative of hotness of 0%.  Since
the inlined functions effectively disappear you need to tune in the lower
range, thus we need more precision.
