11590	cpp_int initialization inefficient	Manfred Weis <manfredweis@…>	John Maddock	"I tried to create an cpp_int with about 10 million digits from a hex string ""0x1....1""; it literally take ages.
The reasons seems to be the repeated shift and add conversion from the characters; while that is inevitable for decimal digits, a hex encoded string would allow to directly determine the final position and shift in the corresponding limb. 

TODO: check supplied string for valid hex encoding, allocate enough zero-initialized limbs and then directly set the value of the corresponding limb.

A further improvement would be to supply a conversion from a sequence of values that are stored in some linear container."	Patches	closed	To Be Determined	multiprecision	Boost 1.57.0	Optimization	fixed
