7a6ebecf9e math.c: C99-like atan2 
* math.c (math_atan2): return values like as expected by C99 if
  both two arguments are infinity.  based on the patch by cremno
  phobia <cremno AT mail.ru> in [ruby-core:62310].  [Feature #9799]

6e34259271 test_math.rb: rename check as assert_float 
* test/ruby/test_math.rb (assert_float): rename with `assert_`
  prefix so that the caller frame would appear in backtraces.

38656e24be math.c: check domain of base argument 
* math.c (math_log): check domain of base argument too.  raises
  Math::DomainError instead of returning NaN if the base is less
  than 0, and returns NaN instead of -infinity if both of two
  arguments are 0.  [ruby-core:62309] [Bug #9797]
