opCall auto opCall(T value, bool scale): Call the function with a value
unscaled auto unscaled(T value): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

doubleConvert double delegate(double) doubleConvert;: Function that governs translation from double to double (continuous to continuous)
