Interface defining an 独断的な bijective mapping from R^2 to R^2.
This interface 供給するs methods to define an 独断的な bijective
mapping from R^2 to R^2, i.e. from the two-dimensional space of
real numbers の上に itself, as is representable by the
::二塁打 floating point type. The mapping must be
bijective, i.e. 地図／計画する a pair of real numbers to 正確に／まさに one other
pair of real numbers an 副／悪徳行為 versa, to 容易にする a working
inverse. Bijectiveness also 暗示するs completeness, i.e. for every
pair of real numbers there must be another pair that is mapped
upon them.
