decodeFloat(forKey:)
Decodes a single-precision floating-point value associated with a given key.
Declaration
func decodeFloat(forKey key: String) -> FloatParameters
- key:
A key in the archive within the current decoding scope.
keymust not benil.
Return Value
The single-precision floating-point value associated with the key key. Returns 0.0 if key does not exist.
Discussion
If the archived value was encoded as double precision, the type is coerced, loosing precision. If the archived value is too large for single precision, the method raises an NSRangeException.
