/emsr/cxx_math_const.svg?branch=master)](https://travis-ci.org/emsr/cxx_math_const) Implement standard and Gnu extension math constants. The OpenGL folks have ideas about C++ constants.
##Goals and Ideas:
-
Implement Lev's ideas.
-
Comment OEIS everywhere if available and findable.
-
Implement multi-word constants. One way to view a constant implemented as an unevaluated sum of several floating- point values is as a polynomial in t = B^-q where B is the base of the floating-point number and q <= p where p is the precision of the number.
For double we could use full 53-bit constants and t = 2^{-53}. We could use 52-bit constants expressed as 13-digit hex constants and t = 2^{-52}. -
Consider rounding. For the standard we need to consider this in "commitee". We should leave room for it in a future standard. We might have to say something about what you get now though.
-
I think the presence of invsqrt3_t and not invsqrt3_t in Lev's proposal is an oversight.
