numeric.c: Numeric#positive? and Numeric#negative?
* numeric.c (num_positive_p, num_negative_p): add methods
Numeric#positive? and Numeric#negative?.
[ruby-core:69173] [Feature #11151]
* numeric.c (flo_positive_p, flo_negative_p): specialiazed
functions for Float.
* complex.c (Init_Complex): Complex do not have positive? and
negative? methods
