Function ARRAY-TOTAL-SIZE

Syntax:

array-total-size array => size

Arguments and Values:

array---an array.

size---a non-negative integer.

Description:

Returns the array total size of the array.

Examples:

     (array-total-size (make-array 4)) =>  4
     (array-total-size (make-array 4 :fill-pointer 2)) =>  4
     (array-total-size (make-array 0)) =>  0
     (array-total-size (make-array '(4 2))) =>  8
     (array-total-size (make-array '(4 0))) =>  0
     (array-total-size (make-array '())) =>  1

Affected By: None.

Exceptional Situations:

Should signal an error of type type-error if its argument is not an array.

See Also:

make-array, array-dimensions

Notes:

If the array is a vector with a fill pointer, the fill pointer is ignored when calculating the array total size.

Since the product of no arguments is one, the array total size of a zero-dimensional array is one.

     (array-total-size x)
        ==  (apply #'* (array-dimensions x))
        ==  (reduce #'* (array-dimensions x))
