LREAL_TO_STRING

LREAL into STRING

The function LREAL_TO_STRING converts a value from the data type LREAL into a value of the data type STRING[64], which has 7 spaces both before and after the decimal point. The resulting string is right justified within the range '-999999.0000000' to '9999999.0000000'. The plus sign is omitted in the positive range. Leading zeros are filled with empty spaces (e.g. out of -12.0 the STRING '-12.0').

Unnamed output (STRING): Conversion resultSTRING[15]

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
		lrValue: LREAL:=5.983e5;
		bStart: BOOL:=FALSE;
		sResult: STRING[64]:='';
	END_VAR

LD body

When the variable bStart is set to TRUE, the function is carried out.
