UDINT_TO_STRING_LEFT_ALIGNED

Unsigned DOUBLE INTEGER into left-aligned STRING

It converts a value of the data type UDINT into a value of the data type STRING in left-aligned decimal representation.

Parameters

Input

UDINT: Input data type

Output

STRING: Conversion result

Remarks

Explanation

Function used	String1 defined as	Result
String1:= UDINT_TO_STRING_LEFT_ALIGNED(-12345678)	STRING[2]	'-1'
	STRING[4]	'-123'
	STRING[6]	'-12345'
	STRING[8]	'-1234567'
	STRING[10]	'-12345678'
	STRING[12]	'-12345678'
	and so on...

NOTE

When using the data type STRING with small PLCs like FP-e or FP0, make sure that the length of the result string is equal to or greater than the length of the source string.

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		udiValue: UDINT:=12345678;
			(*example value*)
		sResult: STRING[11]:='';
			(*result: here '12345678'*)
	END_VAR
