Use littleEndian for limb-endianness: bigEndian arch are very rare, untestable in CI, a pain to maintain and an intermediate serialization step instead of casting is cheap 2023-06-12 17:11:14 +07:00

refactoring away for loop macros 
* remove experimental for loop macro usage
* make implementation of several operations follow data structure
(recursive data -> recursive implementation)
* rename getSize -> bitsof to avoid bits vs bytes confusion
* fix potential 32-bit issue where asSignedWords cast to `int` even when
`uint64` was used as storage
* `hi` for signed ints now is signed - this replaces `asSignedWords` and
makes several int operations more natural
* fix bit size assert

zah 6ae8de932d Add explicit generic conversion operators (#56) 
The new `to` operators that can be used to constuct Stint types from
regular integer types. These are intented for usage in generic code
such as rlp.nim

Also fixes a bug preventing construction of Stint values from unsigned
integers (because they lack an unary `-` operator).

Compile-time creation of Uint (#53) 
* Start on allowing compile-time stint. Works for Uint256

* remove and reorder initUintImpl, zero and one procs

* Fix assignation of uint64 to 2xuint32, remove unsafeConv and use const for base/radix

* assign_least_significant_words shouldn't implicitly capture result

* Simplify least significant words macros
