Data processing (scientific notation to data, invalid zero after removing data)

1. Convert scientific notation to decimal:

function transfor(inputNumber){
   if (isNaN(inputNumber)) {
       return inputNumber;
   }
   inputNumber = '' + inputNumber;
   inputNumber = parseFloat(inputNumber);
   let eformat = inputNumber.toExponential() // 转换为标准的科学计数法形式（字符串）
   let tmpArray = eformat.match(/\d(?:\.(\d*))?e([+-]\d+)/) // 分离出小数值和指数值
   let number = inputNumber.toFixed(Math.max(0, (tmpArray[1] || '').length - tmpArray[2]));
   return number;
}

2. Remove invalid zeros at the end of the data:

parseFloat(number)

3. Intercept the decimal to eight digits, and display the original data if less than eight digits

function transfor(result){
    let float = '';
    let int = '';
    if(result && result.indexOf('.') > -1){
       int = result.split(".")[0];
       let num1 = result.split(".")[1];
       if(num1.length > 8){
          float = num1.slice(0,8);
          if(/^[0]/.test(float)){
             return 0;
          }else{
             return int + '.' + float;
          }
       }else{
          return result;
       }
     }else{
        return result;
     } 
}
