What I did¶

require 'bigdecimal' r = 0.04...(Float::INFINITY) n = BigDecimal.new('0.13E0') r.include?(n.to_f) r.include?(n) 

What I expected¶

true true 

What happens instead¶

true FloatDomainError: Infinity	from (irb):19:in `to_r'	from (irb):19:in `<=>'	from (irb):19:in `include?'	from (irb):19	from /Users/msiegel/.rvm/rubies/ruby-2.2.3/bin/irb:15:in `<main>' 

Workaround¶

To workaround, I am calling #to_f on the BigDecimal before submitting it to the Range#include?

Note that this exception only occurs for certain BigDecimal values, not for all.
