Re: [julia-users] Re: How to get first number from Int64

One solution is to make sure you're using the current release version of 
Julia: parse(Int,string(lista[3])[1]) works as intended.

If you do a:

 precomp = map(log10,2:10)

Then a oneliner for the first digit is:

 searchsortedfirst(precomp, log10(lista[3])%1.0)

There are many paths in the garden. But this one is not as long (slow) as 
it looks.
