Hi, I need to extract the first digit after the decimal point from a number such as 28.56018, which should be '5'.Since no one came up with the simple solution: $num = "28.56018"; ereg("^[0-9]+\.([0-9]){1}", trim($num), $regs); if($regs[1]) $digit = $regs[1]; else print "no digit found"; -- Kind regards Kim Emax
