Luke Parker d6435b37ef Stop single digit strings from throwing an IndexError on `parse` (#59) 2018-08-05 23:47:05 +02:00
Zahary Karadjov 406f1aa317 Added a fromHex helper in the style of the new fromBytes APIs 2018-07-04 18:37:07 +03:00
zah f05feeb865 Relaxed construction from BE bytes (#57) 
* Support automatic padding when constructing values from byte arrays

* add a test case for fromBytesBE
 2018-07-04 17:34:14 +02:00
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 signed ints (#55) 
* Refactor asSignedWords, kill 130+ lines

* Allow signed int initialization at compiletime.

* inline procs in uint_mul

* Fix an unfortunate shadowing in high(Int)

Uint - allow compile-time evaluation for all procs (#54) 
* Initial commit - allow all ops at compile-time on uint.

* Update benchmark

* Delete commented ideal version of asWordsiterate, it  is obvious from the workaround (and is tracked in the PR)

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
