* I do not use 1.9.3
* Also keeping them in each file increases mental overhead (true it *can* be autoamted)
* None of the files encodes NON ASCII chars.
* I do not expect it makes any difference, since nobody programmatically
will consume strings generated by mutant under the assumption they are UTF-8 encoded.
* 1.9.3 Users have to deal with the encoding fuckup under ruby anyways.
There are two representations of zero in IEEE 754. The negative and the
positive zero. This commutis removes a mutation that causes the sign to be flipped.
These mutations are very uneasy to kill. Currently only these side
effects are known:
1 / -0.0 => -Infinity
1 / 0.0 => Infinity
0.0.to_s => "0.0"
-0.0.to_s => "-0.0"
I'm happy to readd the mutation - when someone adds more wisdom to
this case ;)
Closes#126
