# BigDecimal.- (from ruby core) --- self - value -> bigdecimal --- Returns the BigDecimal difference of `self` and `value`: b = BigDecimal('333333.333') # => 0.333333333e6 b - 2 # => 0.333331333e6 b - 2.0 # => 0.333331333e6 b - Rational(2, 1) # => 0.333331333e6 b - Complex(2, 0) # => (0.333331333e6+0i) See the [Note About Precision](BigDecimal.html#class-BigDecimal-label-A+Note+About+Precision ).
