z NumToHexString
The NumToHexString instruction converts integer In to a hexadecimal text string of UTF-8 alphanu-
meric characters. If In is negative, it is expressed in its two’s complement (bits inverted and then 1
added).
For either instruction, the number of characters in text string Out is adjusted to number of characters L.
If there are not enough characters, the upper digits are filled with fill character Fill. If the number of char-
acters in the conversion result exceeds L, L characters from the lower digits of the conversion result are
assigned to Out. The NULL character is not included in the number of characters.
The data type of Fill is enumerated type _eFILL_CHR. The meaning of the enumerators are as follows:
The following examples are for the NumToDecString instruction.
