to_bytes_unsigned

Convert this non-negative big_integer to a byte array, with no sign bit.

The generated byte array has more significant bits on the left and less significant bits on the right (big-endian).

Inverse of big_integer.from_bytes_unsigned().

When this big_integer is equal to 0, the empty byte array x'' is returned (this is consistent with the inverse function big_integer.from_bytes_unsigned(), which interprets x'' as 0).

Examples:

• 0L.to_bytes_unsigned() returns x''

• (-1L).to_bytes_unsigned() throws an exception

• 1L.to_bytes_unsigned() returns x'01'

• 2L.pow(100).to_bytes_unsigned() returns x'10000000000000000000000000'
