Let's say that I have the following float/double: 137.837
How can I find how many places from left the dot appears? So in
this example I want to take either three or four (depending on
how you think it). Does anyone knows how I can do that and can
explain it to me?
See the https://en.wikipedia.org/wiki/Common_logarithm fpr the
explanations.
```
import std.stdio, std.math;
void main(string[] args)
{
alias numDigits = (f) => log10(f + 0.5).ceil();
}
