* Value
* Updated the type system's behavior, in order to better support backwards
compatibility with code that was written before 64-bit integer support was
introduced. Here's how it works now:
- 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 represented as that type. In particular, a value
constructed with a double like 17.0 will now return true for all of
these methods.
* 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 however that the conversion may not be exact -- for
example, doubles cannot exactly represent all integers above 2^53 + 1.
* 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.
* isConvertibleTo(fooValue) indicates that it is safe to call asFoo.
(For each type foo, isFoo always implies isConvertibleTo(fooValue).)
asFoo returns an approximate or exact representation as appropriate.
For example, a double value may be truncated when asInt is called.
* For backwards compatibility with old code, isConvertibleTo(intValue)
may return false even if type() == intValue. This is because the value
may have been constructed with a 64-bit integer larger than maxInt,
and calling asInt() would cause an exception. If you're writing new
code, use isInt64 to find out whether the value is exactly
representable using an Int64, or asDouble() combined with minInt64 and
maxInt64 to figure out whether it is approximately representable.
* isBool, isNull, isString, isArray, and isObject now return true if and
only if the value is of that type.
