Detailed Description

Arbitrary precision integer type.

Local storage format

Internally the big integer is stored in an array of mp_word_t ordered little-endian alike, with the least significant word at the array-bottom and most significant word at the array-top.

The mp_word_t itself is stored in jau::endian::native!
