Generate a random array

and simple two test function

M f M norme 11 line :

M g M norme M norme 21 line :

M r M norme :

A 100100 RND :

to 0 time :

A f 57.9134

0 time to - 0.15 s *

Two questions:

to 0 time :

A r 57.5818

0 time to - 0.126 s *

to 0 time :

A g 57.5976

0 time to - 0.085 s *

Well, are different because A isn't parsed as a true numeric array. Using eval now are the same:

A 100100 RND eval :

to 0 time :

A f 57.6967

0 time to - 0.141 s *

Remain the second question.

to 0 time :

A r 57.5818

0 time to - 0.126 s *

to 0 time :

A g 57.6967

0 time to - 0.062 s *

BTW, we now are sure that with eval() we can parse A as a numberic entity, and can't do nothing for speed up a procedure involving A. NDTM Amarasekera shows that's false. Here an example

M h m M 1 el : k 2 M length range m M k el < m M k el : continue if for m 31 line :

Mo h' M Mo : m M 1 el : k 2 M length range m M k el < m M k el : continue if for m 41 line :

A 7575 RND eval :

to 0 time :

A h 0.9998

0 time to - 10.824 s *

to 0 time :

A h' 0.9998

0 time to - 0.263 s *
