Add tests of more strtod special cases
|
||
|
|
|
||
|
|
There is very little test coverage of inputs to strtod-family
|
||
|
|
functions that don't contain anything that can be parsed as a number
|
||
|
|
(one test of ".y" in tst-strtod2), and none that I can see of skipping
|
||
|
|
initial whitespace. Add some tests of these things to tst-strtod2.
|
||
|
|
|
||
|
|
Tested for x86_64.
