Subject: [ruby-core:47386] [Backport92 - Backport #6958][Open] buggy BigDecimal#integer?


Issue #6958 has been reported by adrianomitre (Adriano Mitre).

----------------------------------------
Backport #6958: buggy BigDecimal#integer?
https://bugs.ruby-lang.org/issues/6958

Author: adrianomitre (Adriano Mitre)
Status: Open
Priority: High
Assignee: 
Category: lib
Target version: 


BigDecimal#integer? always return false, which is wrong in many cases, as shown below.

x, y = BigDecimal('1'), BigDecimal('1.0')

x.integer?
#=> false

y.integer?
#=> false

x == x.to_i
#=> true

y == y.to_i
#=> true

# Possible workaround
#
class BigDecimal
  def integer?
    self == self.to_i
  end
end
