SAS fails to convert all of the CHAR scientific values to numeric

[d6k5d3]

Using the following code

SurvM=input(Surv_M, best32.);

I let SAS strive to convert scientific values stored in CHAR format to numeric BEST32., however, though most of them get converted, I see there are a few left which did not get converted.

What should I do?

Please provide examples of ones that do not get converted.

SurvM=input(Surv_M, E32.);
