I am new in Julia.  
Having a Float64 “1.24543123e6” which I want to print as a string in the Format “1,245,431.23” or “1.245.431,23” (de).

I am looking for something like  
a) string number\_format ( float $number , int $decimals = 0 , string $dec\_point = “.” , string $thousands\_sep = “,” ) [PHP]  
or  
b) Java Class Class NumberFormat / DecimalFormat.

Thanks!

Have you tried using `@printf`?

Yes: @printf(“%12.2f\n”, x)

but I have no idea how to modify the format-string to do the thausends\_seperation.
