Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

I dont know, but if not then you can set a var DecimalValue to 0, then convert the hex number to a string, loop over each character. On each loop:

  1. Set a var DigitValue to 10 for "A", 11 for "B" ... 15 for "F" and of course 0 for "0", 1 for "1" etc.

  2. Set another var SixteensPlace to the lastindex of the whole string minus the loop index.

  3. Multiply DigitValue by the result of 16 raised to the SixteensPlace power, and add that result to DecimalValue.

when the loop is complete, DecimalValue should have the value in Base 10 equivalent to the Hexadecimal value it was given, If I did my math right. I hope i did. You can check it with an online hex to dec converter.
