JS convert numbers to letters

Numbers into letters

a=>1;b=>2;.aa=>27 wait
The essence of the problem is Hexadecimal conversion , The principle of binary conversion is

aaaa = 1×26^3 + 1×26^2 + 1×26^1 + 1×26^0 = 18279
abcd = 1×26^3 + 2×26^2 + 3×26^1 + 4×26^0 = 19010

This leads to a formula for converting letters into numbers . First, get the length of the letter string n, Then a single string is converted into a number （1-26）.

Such as abcdef, You know n=6, transformation ：

1. a×26^(n-1) + b×26^(n-2) + c×26^(n-3) + d×26^(n-4) + e×26^(n-5) + f×26^(n-6)
2. 1×26^(5) + 2×26^(4) + 3×26^(3) + 4×26^(2) + 5×26^(1) + 6×26^(0)

According to this, we can deduce the calculation process of converting numbers into letters ( adopt Remainder To achieve , Note the remainder m by 0 Reset it to 26, because 0 The corresponding letter is z), Give any greater than 0 The natural number of x Yes ：

const number_to_word = (x) => {
    
    let s = "";
    while (x > 0) {
    
      let m = x % 26;
      m = m === 0 ? (m = 26) : m;
      s = String.fromCharCode(96 + parseInt(m)) + s;
      x = (x - m) / 26;
    }
    return s;
  });
};
