Macros for PI
Usually there will always be macros for pi defined in <i>math.h</i>, namely M_PI, M_PI_2, etc... (sometimes they're unavailable, e.g. windoze!). For typesafe definitions, the ecl also defines these as constants in the ecl namespace.
Various regularly used functions are also present - usually in the form of functors (useful for passing around should it ever be necessary).
Not, 'fuzzy logic'...
The bound of the approximation is by default, determined by the machine precision on your machine. If a user specified epsilon bound is preferred, that can be added as an optional third argument to either function.
