1.9.3 から BigMath.#exp でも Fixnum、Float、Rational オブジェクトが指定できるのではないかと思うのですが、Float、Rational については現在は ArgumentError と TypeError になってしまうようです。

puts BigMath.exp(BigDecimal("1.0"), 10) # => 0.2718281828E1
puts BigMath.exp(1, 10) # => 0.2718281828E1
puts BigMath.exp(1.0, 10) # => ArgumentError
puts BigMath.exp(Rational(1, 1), 10) # => TypeError
