Hello, all

within my function I want to set the title of a graphics page with the following code snippet:

the variable ti is read out from an page.info value (I guess it is a double value within the page.info structure)



string legend;
	legend = "\\b(Einspritzverläufe K" + kunde + ")\r\n";
	legend = legend + "\\b(Vergleich der Einzelinjektoren - FUP: " + (int)fup + " [bar],  ";
	legend = legend + "t\-(i, main): " + ti + " [ms])";
	LTCmd = "title.text$ = " + legend;
	LT_execute(LTCmd);


this works so far. But the variable ti shows up as "0.658000000001"
and it should be only "0.658" as lable text!

How can I set the mantisse within a string to enshure it is shown on the graphics page as "0.658"!!

Thanks Hajo

Hi Hajo,

Look up the Format member function in the string class.
You can use that to place values in the string using a specified format.

For example,

	string strPi;
	strPi.Format("Value of pi = %5.2f", pi); 
	printf("%s\n", strPi);
