Metorex

Rational

ruby/spec describes 31 methods in core/rational, and Metorex implements 31 of them. The parameters are what Method#parameters answers under Metorex.

  • Rational#%: implemented, parameters [[:req, :other]]. Returns self modulo other as a real numeric (Integer, Float, or Rational).
  • Rational#*: implemented, parameters [[:req]]. Returns the numeric product of self and other:
  • Rational#**: implemented, parameters [[:req]]. Returns self raised to the power exponent:
  • Rational#+: implemented, parameters [[:req]]. Returns the sum of self and other:
  • Rational#-: implemented, parameters [[:req]]. Returns the difference of self and other:
  • Rational#/: implemented, parameters [[:req]]. Returns the quotient of self and other:
  • Rational#<=>: implemented, parameters [[:req]]. Compares self and other.
  • Rational#==: implemented, parameters [[:req]]. Returns true if rat equals object numerically.
  • Rational#abs: implemented, parameters []. Returns the absolute value of rat. An example calling it.
  • Rational#ceil: implemented, parameters [[:opt, :digits]]. Returns the smallest number greater than or equal to rat with a precision of ndigits decimal digits (default: 0). An example calling it.
  • Rational#denominator: implemented, parameters []. Returns the denominator (always positive). An example calling it.
  • Rational#div: implemented, parameters [[:req, :other]]. Returns the quotient self/other as an integer (via floor), using method / as defined in the subclass of Numeric. An example calling it.
  • Rational#divmod: implemented, parameters [[:req, :other]]. Returns a 2-element array [q, r], where q = (self/other).floor # Quotient. An example calling it.
  • Rational#fdiv: implemented, parameters [[:req, :other]]. Performs division and returns the value as a Float. An example calling it.
  • Rational#floor: implemented, parameters [[:opt, :digits]]. Returns the largest number less than or equal to rat with a precision of ndigits decimal digits (default: 0). An example calling it.
  • Rational#hash: implemented, parameters []. An example calling it.
  • Rational#inspect: implemented, parameters []. Returns the value as a string for inspection. An example calling it.
  • Rational#integer?: implemented, parameters []. Returns true if self is an Integer. An example calling it.
  • Rational#magnitude: implemented, parameters []. Returns the absolute value of rat. An example calling it.
  • Rational#marshal_dump: implemented, parameters [].
  • Rational#numerator: implemented, parameters []. Returns the numerator. An example calling it.
  • Rational#quo: implemented, parameters [[:req, :other]]. Returns the quotient of self and other: An example calling it.
  • Rational#rationalize: implemented, parameters [[:rest, :limits]]. Returns a simpler approximation of the value if the optional argument eps is given (rat-|eps| <= result <= rat+|eps|), self otherwise. An example calling it.
  • Rational#remainder: implemented, parameters [[:req, :other]]. Returns the remainder after dividing self by other. An example calling it.
  • Rational#round: implemented, parameters [[:opt, :digits]]. Returns rat rounded to the nearest value with a precision of ndigits decimal digits (default: 0). An example calling it.
  • Rational#to_f: implemented, parameters []. Returns the value as a Float. An example calling it.
  • Rational#to_i: implemented, parameters []. Returns the truncated value as an integer. An example calling it.
  • Rational#to_r: implemented, parameters []. Returns self. An example calling it.
  • Rational#to_s: implemented, parameters []. Returns the value as a string. An example calling it.
  • Rational#truncate: implemented, parameters [[:opt, :digits]]. Returns rat truncated (toward zero) to a precision of ndigits decimal digits (default: 0). An example calling it.
  • Rational#zero?: implemented, parameters []. Returns true if zero has a zero value, false otherwise. An example calling it.
