Improve performance some Integer and Float methods written by Ruby.

benchmark:

prelude: |
  int_num = 42
  flo_num = 4.2
benchmark:
  integer_real: |
    int_num.real
  float_real: |
    flo_num.real
  integr_imag: |
    int_num.imag
  float_imag: |
    flo_num.imag
  integer_conj: |
    int_num.conj
  float_conj: |
    flo_num.conj
  integer_numerator: |
    int_num.numerator
  integer_denominator: |
    int_num.denominator
loop_count: 20000000
