DWORD_TO_HEXSTR

This function converts a decimal number into a hexadecimal string (base 16).

Return value

Name	Type	Description
DWORD_TO_HEXSTR	T_MaxString

Inputs

VAR_INPUT
    in         : DWORD;
    iPrecision : INT;
    bLoCase    : BOOL;
END_VAR

Name	Type	Description
in	DWORD	The decimal number to be converted.
iPrecision	INT	Minimum number of displayed 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 truncated! If the iPrecision parameter and the in parameter have the value zero, the resulting string is an empty string.
bLoCase	BOOL	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 = ''
