@user63956 Yes it works now I have understand what you mean. Thank You And we can remove the ternary operator cause log10(0) is interpreted as false

@JörgHülsermann -~$x is equivalent to ((int)$x)+1. <?=-~log10(abs($argn?:1)); seems to work.

@JörgHülsermann Why not just $argn?:1? It would be 26 bytes with log10() and abs().

@roberto06 if i use abs for higher numbers the string will be interpreted as 1.0E+64 for example gives back 7 and not 64

Why not simply <?=strlen(abs($argn)); ?

The first one doesn't work, for example, for 10, because ^ has lower priority. You can fix it with -~.
