string to double cast operation..

[ericxbenoit]

Hi,

I would like to cast a string to get a double.

For example I have myString = "23.34" and I want to get myDouble = 23.34

It is not possible to cast string to a double value in the way you suggest. However, you can convert it with the following function from <stdlib.h>

double atof(const char *s) //ascii to float

Or use

sscanf (myString, &quot;%lg&quot;, &myDouble);

That's from double to string, not from string to double...

Uups, sorry, I was out of my mind when I answered this
