Metorex

Float

ruby/spec describes 49 methods in core/float, and Metorex implements 49 of them. The parameters are what Method#parameters answers under Metorex.

  • Float#%: implemented, parameters [[:req, :other]]. Returns self modulo other as a Float.
  • Float#*: implemented, parameters [[:req]]. Returns the numeric product of self and other:
  • Float#**: implemented, parameters [[:req]]. Returns self raised to the power exponent:
  • Float#+: implemented, parameters [[:req]]. Returns the sum of self and other; the result may be inexact (see Float):
  • Float#+@: implemented, parameters []. Returns self.
  • Float#-: implemented, parameters [[:req]]. Returns the difference of self and other:
  • Float#-@: implemented, parameters []. Returns self, negated:
  • Float#/: implemented, parameters [[:req]]. Returns the quotient of self and other:
  • Float#<: implemented, parameters [[:req]]. Returns whether the value of self is less than the value of other; other must be numeric, but may not be Complex:
  • Float#<=: implemented, parameters [[:req]]. Returns whether the value of self is less than or equal to the value of other; other must be numeric, but may not be Complex:
  • Float#<=>: implemented, parameters [[:req]]. Compares self and other.
  • Float#==: implemented, parameters [[:req]]. Returns true if other has the same value as self, false otherwise:
  • Float#===: implemented, parameters [[:req]]. Returns true if other has the same value as self, false otherwise:
  • Float#>: implemented, parameters [[:req]]. Returns true if self is numerically greater than other:
  • Float#>=: implemented, parameters [[:req]]. Returns true if self is numerically greater than or equal to other:
  • Float#abs: implemented, parameters []. Returns the absolute value of self: An example calling it.
  • Float#angle: implemented, parameters []. Returns 0 if self is positive, Math::PI otherwise. An example calling it.
  • Float#arg: implemented, parameters []. Returns 0 if self is positive, Math::PI otherwise. An example calling it.
  • Float#ceil: implemented, parameters [[:opt, :digits]]. Returns a numeric that is a "ceiling" value for self, as specified by the given ndigits, which must be an integer-convertible object. An example calling it.
  • Float#coerce: implemented, parameters [[:req, :other]]. Returns a 2-element array containing other converted to a Float and self: An example calling it.
  • Float#denominator: implemented, parameters []. Returns the denominator (always positive). An example calling it.
  • Float#divmod: implemented, parameters [[:req, :other]]. Returns a 2-element array [q, r], where q = (self/other).floor # Quotient. An example calling it.
  • Float#dup: implemented, parameters []. Returns self. An example calling it.
  • Float#eql?: implemented, parameters [[:req, :other]]. Returns true if other is a Float with the same value as self, false otherwise: An example calling it.
  • Float#fdiv: implemented, parameters [[:req, :other]]. Returns the quotient from dividing self by other: An example calling it.
  • Float#finite?: implemented, parameters []. Returns true if self is not Infinity, -Infinity, or NaN, false otherwise: An example calling it.
  • Float#floor: implemented, parameters [[:opt, :digits]]. Returns a float or integer that is a "floor" value for self, as specified by ndigits, which must be an integer-convertible object. An example calling it.
  • Float#hash: implemented, parameters []. Returns the integer hash value for self. An example calling it.
  • Float#infinite?: implemented, parameters []. Returns: An example calling it.
  • Float#inspect: implemented, parameters []. Returns a string containing a representation of self; depending of the value of self, the string representation may contain: An example calling it.
  • Float#magnitude: implemented, parameters []. Returns the absolute value of self: An example calling it.
  • Float#modulo: implemented, parameters [[:req, :other]]. Returns self modulo other as a Float. An example calling it.
  • Float#nan?: implemented, parameters []. Returns true if self is a NaN, false otherwise. An example calling it.
  • Float#negative?: implemented, parameters []. Returns true if self is less than 0, false otherwise. An example calling it.
  • Float#next_float: implemented, parameters []. Returns the next-larger representable Float. An example calling it.
  • Float#numerator: implemented, parameters []. Returns the numerator. An example calling it.
  • Float#phase: implemented, parameters []. Returns 0 if self is positive, Math::PI otherwise. An example calling it.
  • Float#positive?: implemented, parameters []. Returns true if self is greater than 0, false otherwise. An example calling it.
  • Float#prev_float: implemented, parameters []. Returns the next-smaller representable Float. An example calling it.
  • Float#quo: implemented, parameters [[:req, :other]]. Returns the quotient from dividing self by other: An example calling it.
  • Float#rationalize: implemented, parameters [[:rest, :limits]]. Returns a simpler approximation of the value (flt-|eps| <= result <= flt+|eps|). An example calling it.
  • Float#round: implemented, parameters [[:rest]]. Returns self rounded to the nearest value with a precision of ndigits decimal digits. An example calling it.
  • Float#to_f: implemented, parameters [[:rest, :args]]. Returns self (which is already a Float). An example calling it.
  • Float#to_i: implemented, parameters []. Returns self truncated to an Integer. An example calling it.

  • Float#to_r: implemented, parameters []. Returns the value as a rational. An example calling it.
  • Float#to_s: implemented, parameters []. Returns a string containing a representation of self; depending of the value of self, the string representation may contain: An example calling it.
  • Float#truncate: implemented, parameters [[:opt, :digits]]. Returns self truncated (toward zero) to a precision of ndigits decimal digits. An example calling it.
  • Float#zero?: implemented, parameters []. Returns true if self is 0.0, false otherwise. An example calling it.
