Subject: exponential notation written in invalid form
It appears that numbers with exponential notation are required to contain a decimal point: $ perl -MYAML::XS -e 'print Dump(1e-15)' --- 1e-15 $ irb irb(main):001:0> require 'yaml' => true irb(main):002:0> YAML.load("--- 1e-15").class => String irb(main):003:0> YAML.load("--- 1.0e-15").class => Float

And the same thing applies to NaN and Inf: $ perl -MYAML::XS -e 'print Dump(9**9**9)' --- -nan $ perl -MYAML::XS -e 'print Dump(sin(-9**9**9))' --- inf YAML needs ".nan" and ".inf".

It appears that "1e15" is to be considered a floating point number according to the YAML spec version 1.2 section 10.2 "Recommended Schemas / JSON" but apparently this is not the schema used by ruby. In ruby "1e15" is a string but "1.0e15" is a float.
