Also, it seems to work for fractional small numbers, it doesn't on big one because this function still rely on the toString(radix) method with on my windows 64 bits return a wrong result, should a bug to be filled on Adobe or some else first can confirm those results ?
decimal (10) -> dec2hex -> toString(16) -> real 14159265359 -> 0x34.34BF53E2D -> 0x4BF53E4F -> 0x34BF53E4F 3.14159265359 -> 0x3.243F6A8885D -> 0x3.0 -> 0x3.243F6A8885A308D In between I'll try to find a way to code the correct function.
