Comparing large numbers in php and sql -

-

I need to compare a large number of php (30 digits long) with 2 numbers in my database. What is a good way to do it? I tried to use floats, but it was not accurate enough and I do not have a great way to use a large number of php.

Have you tried to compare the string? Just make sure that each number is padded with zero. 

  mysql> Select "123123123123123123456456456" & lt; "123123123123123123456456457"; + ------------------------------------------------- ------------ + | "123123123123123123456456456" & lt; "123123123123123123456456457" | + ------------------------------------------------- ------------ + | 1 | + -------------------------------------------------

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
