Description

Description:

Checks if one or more flags are set in the given flagset, represented with decimal or hexadecimal number
(Hexadecimal number representation is simply auto-converted into decimal by the engine)
In other words, it simply performs a bitwise AND (&) operation on the two numbers: flags & flagset > 0
To check which flags are present in given flagset use BIS_fnc_bitflagsToArray

Limitations:
Due to various limitations of the Real Virtuality engine this function is intended to work with unsigned 24 bit integers only. This means that the supported range is 2^0...2^24 (1...16777216)

Execution:
