The standard decade values in that range for 1% resistors are 464, 475, 487 and 491.

Given it's actually a bit hard to find 1/10th Watt resistors as anything but precision values anymore and 1% are by far the most common, it would be best to select a resistor value of either 47.5, 48.7 or 49.1 Ohms.

I actually put in 46.4 Ohm resistors there (closest to 47.0) and now I regret it a bit. Oh well, I'll leave it. I have bigger fish to fry at the moment, I have to start considering my antenna options.

Actually, 47 ohms (and 4.7, 470, 4.7k, etc.) is a very standard decade value -- at least in the U.S. market.

These are 1% resistors.

The values you give are for non-precision (5%) resistors, E24 scale.

Some companies make the 5% E24 in 1% also, but the standard for 1% resistors is the E96 values in those tables.
