I'm quite surprised by this since BigDecimal#to_r is available in Ruby for ages

To reproduce:

require 'bigdecimal'



NoMethodError: undefined method `to_r' for 0.15e1:BigDecimal
Did you mean?  to_i
	from (irb):2
	from ~/.rubies/truffleruby-1.0.0-rc10/bin/irb:29:in `<main>'

I've added support for BigDecimal#to_r in e3a61d5. This should be available in the TruffleRuby 1.0.0 RC 12 release. NB: there are other BigDecimal methods not yet implemented. I'll work through the list of them, but I wanted to get a fix out for your immediate problem.

@deepj TruffleRuby 1.0.0 RC 12 is now available with this method added. Please give the release a try and let me know if you run into problems with the method. Thanks again for filing an issue!
