    JSVAL_TO_DOUBLE

    Obsolete since JSAPI 32
    This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

    Casts a given jsval to a jsdouble without any type checking or error handling.

    Syntax

    jsdouble
    JSVAL_TO_DOUBLE(jsval v);
    

    Description

    JSVAL_TO_DOUBLE casts a specified JS value, v, to a C floating-point number of type jsdouble. As a precondition, JSVAL_IS_DOUBLE(v) must be true. This function is not type-safe: if v is an integer, string, null, or anything else, the behavior is undefined.

    To convert any value to a number, use JS_ValueToNumber instead.
