Converting A Double To A String

[jfendt]

In LabWindows CVI, is there a way to convert a double data type into a string?

You can do something like this.

double number;
char string[256];

sprintf(string, "%f", number);

Thanks Sheetal. I'll give that a try.

Hello,

You can use sprintf, but the limitation of this function is that you will need to know how long your double is:

double num;
char str[length of double];

sprintf(str, "%2f", num);


If you want to convert an array of doubles to an array of characters, you could also use the function ConvertArrayType() in the Programmer's Toolbox.


Thanks.

What I was converting isn't an array of doubles. It is just a plain double data type. So I'm not too sure if the ConvertArrayType()function would work in this case. Thank you anyway for your response. I appreciate the help.
