![]() ![]() (zero based, 7DE: E location is 0, D location is 1 and the 7 location is 2) Sum all the multipliers. Multiply every digit with 16 power of digit location. Yes, there's a corresponding loss of precision, but if we accept that for multiplication we should accept it for shifting.Ī reply falls below the community's threshold of quality. Here are the steps to convert hex to decimal: Get the decimal equivalent of hex from table. The other mathemagical operators DTRT when you would overflow an int and auto-promote your data from an int to a double. So unless you know that you won't overflow (and for dealing with 48 bit MACs this means you need to be on a 64 bit machine with a 64 bit perl) then you need to replace all your $i << $j with $i *= 2 ** $j. The << operator overflows if it would go above 32 bits on a 32 bit machine, and the result is undefined. Re: Help with Mac Address to Integer conversion ![]() The substr business in mac_hex2num fixes the problem. Print "$inmac converted to a decimal: $mac\n" Return join(':', $inmac = shift $mac = mac_hex2num($inmac) ![]() My (1.6) sprintf("x", $mac_num % (2**8))) Change the calculator Convert values Round results Enter complex equations using Reverse Polish Notation (RPN) Show decimal points Correct unexpected. I tried using IEEE 754 converter online, but it says the value is out of range. This extension helps you to easily transfer your mac address to different format. $mac_hex = substr(('0'x12).$mac_hex, -12) I want to change a mac address to floating point number.
