New in SVN:
|
||||
-----------
|
||||
|
||||
* Value
|
||||
|
||||
- Updated the Value::isFoo methods to work as follows:
|
||||
|
||||
* isInt, isInt64, isUInt, and isUInt64 return true if and only if the
|
||||
value can be exactly representable as that type. In particular, a value
|
||||
constructed with a double like 17.0 will now return true for all of
|
||||
these methods.
|
||||
|
||||
* isDouble and isFloat now return true for all numeric values, since all
|
||||
numeric values can be converted to a double or float without
|
||||
truncation. Note that the conversion may not be exact -- for example,
|
||||
doubles cannot exactly represent integers above 2^53.
|
||||
|
||||
* isBool, isNull, isString, isArray, and isObject now return true if and
|
||||
only if the value is of that type.
