My prime program
has been created that searches for prime numbers
according to formula of origin topic
but I feel an error in line
s = s + (Cos(3.1416 * (f + 1) / j)) ^ 2 ' FORMULA
I create a version of my prime program about primes
in JavaScript where all numbers are long
by copying save HTM or checked online
https://jdoodle.com/h/2XK
Moreover results of BAS & JS are same
I think there is a mistake in formula

Russia looks world from future. Big data is peace data.
I never recommend anything & always write only about myself
