Entry: JSVAL_TO_DOUBLE (Macro)
Summary: Casts the type flag for a specified JS value and returns a pointer to the value cast as a JS double.
Syntax:
JSVAL_TO_DOUBLE(v)
Description:
JSVAL_TO_DOUBLE casts a specified JS value, v, to a JS double. It does so by casting the value's type tag and casting the result to a double pointer.
Clearing v to a double pointer manipulates its underlying type tag. It does not convert the value stored in v to a different data type. To perform actual data conversion, use the JS_ValueToNumber function.
