问题 What is the full list of suffixes you can use on PowerShell number literals?

问题 Using insert , I push values to an Array as: myarray=[22,33,44] myarray.insert(0,02) # => [2,22,33,44] If do the following, I get: myarray.insert(0,020) # => [16,2,22,33,44] 020 becomes 16 ? If I do the following, I get: myarray.insert(0,0200) # => [128,16,2,22,33,44] 0200 becomes 128 ? May I know the reason for this? 回答1: If the number has a zero in front of it, ruby treats it as an octal number (base 8) You can do similar with binary/hexadecimal too 0x20 => 32 (hexadecimal) 020 => 16 (octal
