I'm running a calculation that outputs a matplotlib plot with a vertical axis scaled with (see image below).

~1e-9-4.998e-1

This is very weird scaling and I'd like to make sure I understand the notation correctly. Does it mean the following?

0.000000001 - 0.4998 = -0.499799999

So far I haven't been able to successfully google this. I would really apprechiate if someone could help me clarify this.

@Lagerbaer is right. The first number (1e-9) is the scale of the axes, and the second is a shift. So the tick marked -8.25 really means (-8.25)*1e-9 - 4.9984827e-1, or -0.00000000825 - 0.49984827 = -0.49984827825
