10e5 == 10^5 is not true in MATLAB

If you type in
10e5 == 10^5
ans =
logical
0
so 10e5 does NOT mean 10 to the power of 5 but it means 10 to the power of 6.
10e5 == 10^6
ans =
logical
1
What does 10e5 mean then? Is it somewhere in the documentation? I just can't seem to find it, I've been looking for it for quite some time now.
Thanks for the help!

The notation "10e5" means "10 times of 10 to the power of 5," where the "e" represents the exponent of the power of 10 (10^x). So for your example, 1e5 == 10^5.

@chaman lal dewangan - If you think this statement is relevant, then you don't understand floating point numbers. That it happens to work in this instance, but not for the case of 1e5, this is just mathematical happenstance. SOMETIMES, you get lucky in any such test.
1e6==10^6
But to properly use MATLAB, you don't want to leave things to mathematical happenstance, hoping to get lucky. That is just a bad idea.
