scientific notation checker

In Java, when a double or bigdecimal decimal is converted to a string, it is often expressed in scientific notation, and we generally do not want to use scientific notation, which can be done by: DecimalFormat a = new DecimalFormat ( "#,# #0.00000000"); system.out.println (A.format (11111111.0000001000000001)); The

MATLAB is not saved as scientific counting method http://blog.sciencenet.cn/blog-472136-402727.html Often in the expression of MATLAB value, it always put some less than 1 of the number greater than 1000 using scientific notation. This sometimes makes people uncomfortable, and it's bad to write data to a text file every time.So every time I check to find out

This afternoon, a friend wrote an algorithm that converts the input integer or floating-point number to the scientific notation expression. After writing the algorithm, he asked me to help him see if there were any bugs or other issues that were not fully considered. I have been scared by the fact that I have not carefully read it-I have written nearly three hundred lines of code. I didn't say anything abou

(0.003) --- true, if the number is small, 0.003 is displayed normally. $ bool16 is too long. If no value is added, the scientific notation var_dump ($ bool) is displayed. // print the result: bool (true) echo""; Var_dump ($ bool2); // print the result: bool (false) echo""; Var_dump ($ bool3); // print the result: int (0) --- false if ($ bool3) {echo" --- true ";} else {echo "--- false" ;}; echo""; Var_dump

When the number is too long, it turns into scientific notation. the numeric value is obtained from the database. because the value is a little large (50 digits), it is immediately counted by science, how can this problem be avoided ?, 50 digits are indeed big enough. You can use strings for storage, because MYSQL cannot process data types of 50 digits. PHP is naturally not so long as a number. Why does it b

This article describes the PHP implementation of the scientific counting method into the original digital string method, shared for everyone to reference. The specific implementation code is as follows: Copy Code code as follows: function Numtostr ($num) { if (Stripos ($num, ' e ') ===false) return $num; $num = Trim (preg_replace ('/[=\ ' "]/', ', ', $num, 1), '" "); scientific

Some projects may involve importing data from Excel, but if the cell type in Excel is a numeric value, but the content data is too long (such as a bank account), it will be read as a scientific notation by default and easily resolved with the following code. BigDecimal bd = new BigDecimal ("3.40256010353E11");System.out.println (Bd.toplainstring ()); The above Java will be the
