Add more tests of strtod end pointer
|
||
|
|
|
||
|
|
Although there are some tests in tst-strtod2 and tst-strtod3 for the
|
||
|
|
end pointer provided by strtod when it doesn't parse the whole string,
|
||
|
|
they aren't very thorough. Add tests of more such cases to
|
||
|
|
tst-strtod2.
|
||
|
|
|
||
|
|
Tested for x86_64.
