# What does this range notation mean: 0:01 < x < 10:0

I've got a homework problem which states "use a range of 0:01 < x < 10:0"

I'm thinking this would mean the range 0.00, 0.01, 0.02, ... 9.98, 9.99, 10.00

Has anyone seen this notation before that can tell me what this range would be?

Thanks, Joe

Could you please describe the context of the problem? – Weltschmerz Aug 30 '11 at 2:10
Sure, here's the problem: Each of the following equations can be represented as a straight line on an x-y plot by choosing the appropriate axis scales. Plot them both in rectangular coordinate format and then in an appropriate format to yield a straight line. Explain how the plot operation yields the straight line. Variable y has units of volts. Variable x has units of meters (use a range of 0:01 < x < 10:0). Note: This is easily done using a spreadsheet program where you can compare the use of different axis scales. – Joe Blitzer Aug 30 '11 at 2:23
You might want to edit that into your question. That being said, I don't know why they're using ":"... – J. M. Aug 30 '11 at 2:32

I don't know what $0{:}01$ means, but if it means $0.01$ then what a range of $0{:}01<x<10{:}0$ means is that $x$ is greater than $0.01$ meters and less than $10$ meters. I suppose the $0$ is excluded so that you can take logarithms.
I think all it means is, when you plot your points, use only values of $x$ between $.01$ and $10$. But I am confused as to why someone would write $0{:}01$ and $10{:}0$ instead of $0.01$ and $10.0$.
