Documentation

A new documentation for ImHex (mainly the pattern language right now) is in the works and can be found here: https://imhex.werwolv.net/docs. It is a lot more detailed than the one found on the Wiki here and contains information about all the new features as well. Check it out!

Changelog

Additions

• Added File Utils

• Added std::ctype to inspect ASCII character traits
• Added std::fxpt with fixed point number conversion and arithmetic
• Added std::limits with minimal and maximal values for different data types
• Added std::math with common math functions
