Integer

generate_bitmask(n)

Return an n-bits integer where every bit is set to 1.

INPUT:

  • n – integer; a positive integer.

EXAMPLES:

sage: from claasp.utils.integer import generate_bitmask
sage: bin(generate_bitmask(4))
'0b1111'
sage: hex(generate_bitmask(32))
'0xffffffff'
to_binary(x, n)

Return the n-bits binary form of x in bitwise little-endian ordering.

INPUT:

  • x – integer

  • n – integer

EXAMPLES:

sage: from claasp.utils.integer import to_binary
sage: to_binary(0x67452301, 32)
