Convert float value to double in objective c

Question

I have use the cast to convert a string to int, a string to double and it works.

Now I want to convert a float value to double and xcode tell me:

"Pointer cannot be cast to type 'double'",

My float variable is declared in .h

@property float *valueX, *valueY

And in .m I do:

double dou = (double) valorX;

What happen here? Thanks!

Not really sure what you're asking here but I imagine the problem is the * in the float properties.

A float property should be declared as...

@property float valueX;

not

@property float *valueX;

(unless it's a pointer to a float but I doubt that's the case here)

Note

You probably should be doing something like this...

@property (nonatomic, assign) CGFloat valueX;
