parseInt('2e3',10) === 2; //true. This is supposed to be 2...

Remove non-ascii character in string
...only characters that has value from zero to 127 are valid. (0x7F is 127 in hex). This code matches all characters that are not in the ascii range and removes them.

It is somewhat open to debate whether you should explicitly convert the pointers with a (void *) cast. It is being explicit, which is usually good (so i...
