29.8.2 Mathematical constants [math.constants]

The library-defined partial specializations of mathematical constant variable templates are initialized with the nearest representable values ofe,,,π,,,ln2,ln10,,,, the Euler-Mascheroni γ constant, and the golden ratio φ constant , respectively.

Pursuant to [namespace.std], a program may partially or explicitly specialize a mathematical constant variable template provided that the specialization depends on a program-defined type.

A program that instantiates a primary template of a mathematical constant variable template is ill-formed.
