Closes #5211
This PR removes one test value that was overflowing to
Inf
as a result of a recent change in precision in cuDF. It also adds exact tests for reading small floating-point values from CSV.We already have documentation explaining that numbers in certain ranges, such as
1.7976931348623158E308 <= x < 1.7976931348623159E308
will have different behavior between CPU and GPU and the number removed from the test (1.7976931348623158E308
) was within this range so I don't think any documentation update is required.
