Thread: Need some help with atof()

Code:

aperture is a string
int ApertureNumber;
ApertureNumber = atof(&aperture[1]);

Will this work if aperture is a string ? If not how would I do this ,
convert string --> float ( it needs to start reading from the second character ).
I had a look at Taurus's thread , and iI want to do exactly the same as what him , however unlike him I'm using strings - should I use strtol() instead ? If that is the case can you explain how would I use it in this case ? Thanks a lot

When I compile it , I get 0.0000000 for the value :

Code:

						int ApertureNumber;
						ApertureNumber = atof(&guess[1]);
						fprintf(output,"The integer representation is : %f",&ApertureNumber);

> You keep adding and removing things at random, like where the hell did this & come from for printing the result?
I'm not sure I understand , are you saying it should be :

Code:

fprintf(output,"The integer representation is : %f", ApertureNumber);

without an & ?

Code:

fprintf(output,"The integer representation is : %f", ApertureNumber);

Have a look at this example fprintf

So float ApertureNumber ? I tried it just now and it retrns a huge number

Code:

#include <stdlib.h>

would help a lot.

IT WORKS Thank you VERY much for that ZuK
