Is there a safe way to "convert" a CGFloat to a NSNumber ?

NSNumber has the numberWithFloat: and numberWithDouble: methods but CGFloat being defined as float or double depending on the platform, it seems risky to use either one of them.

Or is numberWithDouble: safe to use with a CGFloat, as it is the one with the more precision ?

@(myCGFloat)
