acos
Das ist nun zwar grober Blödsinn, aber so könnte man es auch lösen:
class MyFloat
def initialize value
begin
@value = Float value
rescue ArgumentError, TypeError
raise TypeError, 'Must be initialized with a Float-like value'
end
freeze
end
def method_missing method, *args, &block
case method
when :acos
raise NoMethodError, "undefined method `#{method}` for #{self}"
unless (-1.0..1.0).include? @value
Math.acos @value
else
return @value.public_send method, *args, &block if
@value.respond_to? method
super
end
end
def respond_to_missing? method, include_private = false
case method
when :acos
(-1.0..1.0).include? @value
else
@value.respond_to?(method, include_private) || super
end
end
def self.try_build value
new value
rescue TypeError
nil
end
end
f1 = MyFloat.new 0.4
f2 = MyFloat.new 1.2
p f1.respond_to? :acos # => true
p f2.respond_to? :acos # => false
p f1.acos # => 1.1592794807274085
p f2.acos # => raises NoMethodError
