erf and erfc are missing float versions, so I import them from openlibm. erf is used from Poincare::NormalDistribution:: StandardNormalCumulativeDistributiveFunctionAtAbscissa<float>, and erfc is used (?) just from MicroPython. To clarify, if there is no float version of a function like erf, but there is a double version, C++ promotes the possible float parameter to double and soft-float hilarity ensues.
