    iPrecision : INT;
    bLoCase    : BOOL;
END_VAR

in: The decimal number requiring conversion.

iPrecision: Minimum number of displayed digits (digits). If the actual number of significant digits is less than the iPrecision parameter, the resulting string is filled with zeros from the left. If the number of significant digits is greater than the iPrecision parameter, the resulting string is not cut off! If the iPrecision parameter and the in parameter are zero, the resulting string is empty.

bLoCase: This parameter determines whether lower or upper case letters are used in the conversion. FALSE => "ABCDEF", TRUE => "abcdef".

Example:

PROGRAM MAIN
VAR
    s1   : STRING;
    s2   : STRING;
    s3   : STRING;
    s4   : STRING;
    nCnt : WORD;
END_VAR

nCnt := 43981;
s1   := DWORD_TO_HEXSTR( nCnt, 1, FALSE );
s2   := DWORD_TO_HEXSTR( nCnt, 1, TRUE );
nCnt := 15;
s3   := DWORD_TO_HEXSTR( nCnt, 4, FALSE );
nCnt := 0;
s4   := DWORD_TO_HEXSTR( nCnt, 0, FALSE );

The result:

s1 = 'ABCD'

s2 = 'abcd'

s3 = '000F'

s4 = ''
