A spreadsheet for finding specific resistor ratios

[RnDMonkey]

For my first post, I present my favorite spreadsheet I've ever made (in terms of how consistently I've used it over the years).

This is a spreadsheet I made about 6 years ago for calculating precise resistor ratios for voltage regulators using standard E96 resistor values. As a side-benefit, it's a really convenient list of standard resistor values. I think it's pretty easy and useful.
