I figured out a way to test for bits. It couldn't be easier!!!
mod(int (number/base^bit),bit
Example: If you want to know what the 3 bit of 150 is in
binary numbers.
mod(int (150/2^2),2
Example2 If you want to know what the 4th digit is of 23453 in base 10.
mod(int (23453/10^3),10
or the 2nd digit
mod(int (23453/10^1),10
this couldn't be easier!!!
To put bits into the number N:
to put 1 into bit 3
N+1*2^2->N
to put 1 into bit 5
N+1*2^4->N
to take out bit 2 if it is set.
N-1*2^1->N
to put 0 into anything, do nothing.
You might have to put an if statement for things to come out
right. Ex: to see if bit 5 is set and if it is, reset it.
:if mod(int (N/2^4),2)==1
:then
:N-1*2^4->N
:else
:goto next
:end
Hope this helps.
