  sprintf("%0.#{places}f", value.round(places))
end

def fmt_date(date)
  return nil if date.blank?
  return nil unless (date.is_a?(String) || date.is_a?(Date) || date.is_a?(Time))
  unless date.is_a?(String)
    date = date.to_s(:date4)
  end
  m,d,y = date.split('/')
  "#{m.to_i}/#{d.to_i}/#{y.to_i}"
end

#split_name(name) ⇒ Object

Splits a name into First, Middle, and Last parts.

Returns an array containing [ First, Middle, Last ] Any part that is missing will be nil.

'John Doe'          => [ 'John', nil, 'Doe' ]
'Doe, John'         => [ 'John', nil, 'Doe' ]
'John A. Doe'       => [ 'John', 'A.', 'Doe' ]
'Doe, John A.'      => [ 'John', 'A.', 'Doe' ]
'John A. Doe Jr.'   => [ 'John', 'A.', 'Doe Jr.' ]
'Doe Jr., John A.'  => [ 'John', 'A.', 'Doe Jr.' ]

Since it doesn’t check very hard, there are some known bugs as well.

'John Doe Jr.'      => [ 'John', 'Doe', 'Jr.' ]
'John Doe, Jr.'     => [ 'Jr.', nil, 'John Doe' ]
'Doe, John A., Jr.' => [ 'John', 'A., Jr.', 'Doe' ]

It should work in most cases.
