Question

What does -3.4 E + 38 mean? (In normal number terms).

Answer 1

is that -3.4^38 ?

Answer 2

That means -340000000000000000000000000000000000000.

Answer 3

-3.4x10^38

Answer 4

Oh! Thanks @across :) so the +38 means plus thirty eight zeroes right?

Answer 5

Basically yes. If it were -38, you'd move the decimal place the other direction, such that it would become -0.0000000...034.

Answer 6

oh. and what does 172.5E5 mean?

Answer 7

It means 17250000.

Answer 8

so -3.4 E +38 could also be written as -3.4E39? (39 cuz the 4 comes after the decimal)

Answer 9

No. -3.4*10^38 (note that this is the same as -3.4E+38 it's just a slightly different, and I'd say probably more common, notation) is equivalent to -0.34*10^39.
