31:T4b1,{ const eSeries = serializer(palette) return md` The **E series** is a system of [preferred numbers](https://en.wikipedia.org/wiki/Preferred_number) derived for resistors, capacitors, inductors, and zener diodes. It consists of the series ${eSeries.names}. An E series divides a **decade magnitude** into ${eSeries.list} distinct values. A decade magnitude is a factor of 10 difference between two numbers, e.g. 1–10, 10–100. The number after the 'E' designates its **resolution**, the number of distinct values in the series, and is equal to ${tex`3 \cdot 2^x`}, with ${tex`x \in [0\mathellipsis ${max}]`}. Also, the series’ resolution implies its **tolerance**. For example, in the E${E(eIndex)} series, ${E(eIndex)} consecutive blocks of ${E(max)/E(eIndex)} of the ${E(max)} consecutive values map to a single distinct value in that series. The series’ values have a tolerance of ${v.percentage}. Each series is a proper subset of the next. That is, > ${eSeries.subsets}. Note that the number of digits or **precision** changes between two and three to reflect the precision, in order to be able to distinguish between all values (that is, to create unique values in a series). ` }32:T5b1,basecodes = [ { color: null , multiplier: null, tolerance: .2000, precision: 2 , code: null, letter: "M" , }, { color: "pink" , multiplier: -3 , tolerance: null , precision: null, code: "PK", letter: null, }, { color: "silver", multiplier: -2 , tolerance: .1000, precision: 2 , code: "SR", letter: "K" , }, { color: "gold" , multiplier: -1 , tolerance: .0500, precision: 2 , code: "GD", letter: "J" , }, { color: "black" , multiplier: 0 , tolerance: null , precision: null, code: "BK", letter: null, }, { color: "brown" , multiplier: +1 , tolerance: .0100, precision: 2 , code: "BN", letter: "F" , }, { color: "red" , multiplier: +2 , tolerance: .0200, precision: 3 , code: "RD", letter: "G" , }, { color: "orange", multiplier: +3 , tolerance: .0005, precision: 3 , code: "OG", letter: "W" , }, { color: "yellow", multiplier: +4 , tolerance: .0002, precision: 3 , code: "YE", letter: "P" , }, { color: "green" , multiplier: +5 , tolerance: .0050, precision: 3 , code: "GN", letter: "D" , }, { color: "blue" , multiplier: +6 , tolerance: .0025, precision: 3 , code: "BU", letter: "C" , }, { color: "violet", multiplier: +7 , tolerance: .0010, precision: 3 , code: "VT", letter: "B" , }, { color: "grey" , multiplier: +8 , tolerance: .0001, precision: 3 , code: "GY", letter: "L" , }, { color: "white" , multiplier: +9 , tolerance: null , precision: null, code: null, letter: null, }, ]33:T470,[ { color: null , multiplier: null, tolerance: .2000, precision: 2 , code: null, letter: "M" , }, { color: "silver", multiplier: -2 , tolerance: .1000, precision: 2 , code: "SR", letter: "K" , }, { color: "gold" , multiplier: -1 , tolerance: .0500, precision: 2 , code: "GD", letter: "J" , }, { color: "brown" , multiplier: +1 , tolerance: .0100, precision: 2 , code: "BN", letter: "F" , }, { color: "red" , multiplier: +2 , tolerance: .0200, precision: 3 , code: "RD", letter: "G" , }, { color: "orange", multiplier: +3 , tolerance: .0005, precision: 3 , code: "OG", letter: "W" , }, { color: "yellow", multiplier: +4 , tolerance: .0002, precision: 3 , code: "YE", letter: "P" , }, { color: "green" , multiplier: +5 , tolerance: .0050, precision: 3 , code: "GN", letter: "D" , }, { color: "blue" , multiplier: +6 , tolerance: .0025, precision: 3 , code: "BU", letter: "C" , }, { color: "violet", multiplier: +7 , tolerance: .0010, precision: 3 , code: "VT", letter: "B" , }, { color: "grey" , multiplier: +8 , tolerance: .0001, precision: 3 , code: "GY", letter: "L" , }, ]34:T5b4,basecodesOLD = [ { color: null , multiplier: null, tolerance: .2000, precision: 2 , code: null, letter: "M" , }, { color: "pink" , multiplier: -3 , tolerance: null , precision: null, code: "PK", letter: null, }, { color: "silver", multiplier: -2 , tolerance: .1000, precision: 2 , code: "SR", letter: "K" , }, { color: "gold" , multiplier: -1 , tolerance: .0500, precision: 2 , code: "GD", letter: "J" , }, { color: "black" , multiplier: 0 , tolerance: null , precision: null, code: "BK", letter: null, }, { color: "brown" , multiplier: +1 , tolerance: .0100, precision: 3 , code: "BN", letter: "F" , }, { color: "red" , multiplier: +2 , tolerance: .0200, precision: 3 , code: "RD", letter: "G" , }, { color: "orange", multiplier: +3 , tolerance: .0005, precision: 3 , code: "OG", letter: "W" , }, { color: "yellow", multiplier: +4 , tolerance: .0002, precision: 3 , code: "YE", letter: "P" , }, { color: "green" , multiplier: +5 , tolerance: .0050, precision: 3 , code: "GN", letter: "D" , }, { color: "blue" , multiplier: +6 , tolerance: .0025, precision: 3 , code: "BU", letter: "C" , }, { color: "violet", multiplier: +7 , tolerance: .0010, precision: 3 , code: "VT", letter: "B" , }, { color: "grey" , multiplier: +8 , tolerance: .0001, precision: 3 , code: "GY", letter: "L" , }, { color: "white" , multiplier: +9 , tolerance: null , precision: null, code: null, letter: null, }, ]35:T44e,// function z(seriesIndex, scaleIndex, precisionTable = precision) { // // Assistants and shortcuts. // // const precision = precisionTable[seriesIndex] // // const resolution = factor(precisionTable.length - 1) // Total number of distinct values in the scale // // const scaleFraction = scaleIndex / resolution // Where are we on the scale, exactly?
