The standard form of a number converts a large number in short form using the power of 10.
First number is:
1.57828282E5
As you mentioned the numbers are technology generated hence E^x = 10^x. For example, in Matlab, you can write 10^5 as E^5.
Hence, the standard form of the number would be
1.57828282 x 10^5
While the ordinary form would be
157828.282
Similarly, the standard form of the second number would be:
6.82 x 10^-8
