You can directly pass the variable to be filled: parse(nums[i].begin(), nums[i].end(), double_, x); This saves (at least) one double assignment. b) The current code lets Spirit parse from the string iterators, while most of the other codes parse from the plain character buffer. ...
Converts a part of a character string, pointed to by nptr, to a double. The parameter nptr points to a sequence of characters that can be interpreted as a numerical value of the type double. See the “fscanf Family of Formatted Input Functions” on fscanf(), scanf(), sscanf() — Read...
