distance(other)

Returns the distance between self an another value. This is the same as #- but it provides an alternative for common naming between variant classes. 

  4.distance(3)  #=> 1

  def distance(other)
    self - other

round_at(*args)

Conceptually, rounding is expected to apply to floating point numbers. However it can actually be applied to pretty much and Numeric object. For example, one could round an Integer to the nearest kilo. So the actual round.rb lib is in the numeric folder, but we‘ll add this here for convenience.

See Float#round_at.

round_to(*args)

    to_f.round_to(*args)
  end
to_b()

Provides a boolean interpretation of self. If self == 0 then false else true. 

  0.to_b    #=> false
  1.to_b    #=> true
  2.3.to_b  #=> true

# File lib/core/facets/boolean.rb, line 76
  def to_b
    self == 0 ? false : true
