numarray :: multiplying all the elements in 1d array

[Suresh Jeevanandam]

Hi all,
        Lets say I have an array:
        from numarray import *
        a = array([ 6,  7,  8,  9, 10, 11, 12])

        I want to multiply out all the elements and get the result.
        
        r = 1.0
        for i in a:
                r = r*i

        Is there any faster, efficient way of doing this.

Thanks,

regards,
Suresh
