static from7bitToFloat(value) {
    if (value === Infinity) value = 127;

    return Math.min(Math.max(value / 127, 0), 1);
  }
Returns a number between 0 and 1 representing the ratio of the input value divided by 127 (7
bit). The returned value is restricted between 0 and 1 even if the input is greater than 127 or
smaller than 0.

Passing `Infinity` will return `1` and passing `-Infinity` will return `0`. Otherwise, when the
input value cannot be converted to an integer, the method returns 0.

@param value {number} A positive integer between 0 and 127 (inclusive)
@returns {number} A number between 0 and 1 (inclusive)
