NumericHash

Defines a hash whose values are Numeric or additional nested NumericHash‘s.

Common arithmetic methods available on Numeric can be called on NumericHash to affect all values within the NumericHash at once.

Examples

hash1 = NumericHash.new(:a => -1.0, :b => 2)  # => { :a => -1.6, :b => 2 }
hash2 = NumericHash.new(:a => 3, :c => 4)     # => { :a => 3, :c => 4 }
hash1 + hash2                                 # => { :a => 1.4, :b => 2, :c => 4 }
hash1 * 5                                     # => { :a => -8.0, :b => 10 }
-hash1                                        # => { :a => 1.6, :b => -2 }
hash1.round                                   # => { :a => -2, :b => 2 }
