It's human readable. From what I know it's called "Engineer Notation"
We call it floating point.

22e3 for example means 22 * 10^3
the ^ is power
so 22e3 = 22000

in the same maner:
1.2345e3 = 1234.5

or in your case:
993466800: 7.8389333333e+00 8.6850000000e-01
could be written: 993466800: 7.8389333333 0.86850000000
