int_to_bits

include convert.e 
namespace convert 
public function int_to_bits(atom x, integer nbits = 32) 

extracts the lower bits from an integer.

Parameters:

1. x : the atom to convert
2. nbits : the number of bits requested. The default is 32.

Returns:

A sequence, of length nbits, made of 1's and 0's.

Comments:

x should have no fractional part. If it does, then the first "bit" will be an atom between 0 and 2.

The bits are returned lowest first.

For negative numbers the two's complement bit pattern is returned.

You can use operators like subscripting/slicing/and/or/xor/not on entire sequences to manipulate sequences of bits. Shifting of bits and rotating of bits are easy to perform.

Example 1:

s = int_to_bits(177, 8) 
-- s is {1,0,0,0,1,1,0,1} -- "reverse" order
