new impl for erfinv/erfcinv with tests added
remains to change one polynomial evaluation as soon as the maximal degree for horner use will be increased
merging master
improving erf(c)inv and adding tests
 correcting some doxy in euler
correcting some misprints indicated by mathias
suppressing a trailing comment
some blanks not needed
ading some constants used in pow new impl
better accuracy with pow function
Merge branch 'master' into improving_pow
factorizing some code and using load to make the lookup work
it's better to make the work done by pow_abs and let pow just deal with a possible a0<0
bug in exhaustive expx2 test
small correction in nthroot and test added
implement horner without MPL, removes MPL implicit limits
incorrect order for horner, reverse the tuple
polishing includes for combinatorial and modifying anp and cnp
Merge branch 'master' into improving_pow
increase ulp threshold for sne for ATLAS compatibility
Merge pull request #725 from MetaScale/new_horner
