`name`	`const char *`	Name to assign the double.
`flags`	`uint8`	Attributes for the double. Currently these can be 0 or more of the following values `OR`'d: `JSPROP_ENUMERATE`: property is visible in for loops. `JSPROP_READONLY`: property is read-only. `JSPROP_PERMANENT`: property cannot be deleted. `JSPROP_EXPORTED`: property can be exported outside its object. `JSPROP_INDEX`: property is actually an array element.
`spare`	`uint8`	Reserved for future use.

Description

JSConstDoubleSpecs is typically used to define a set of double values that are assigned as properties to an object using JS_DefineConstDoubles. JS_DefineConstDoubles creates one or more double properties for a specified object.

JS_DefineConstDoubles takes an argument that is a pointer to an array of JSConstDoubleSpecs. Each array element defines a single property name and property value to create. The last element of the array must contain zero-valued values. JS_DefineConstDoubles creates one property for each non-zero element in the array.
