decimal to mixed number

Problem description: how to obtain the integer and decimal part of a floating point number Method 1: 1 #include Output:I =-23, FF =-0.0400009 disadvantages: the number of digits in decimal places cannot be precise, because the decimal part is obtained by difference, and pa

In programs, we sometimes need to convert a hexadecimal string to a decimal number. For example:Char * PTR = "0x11 ";Int n = 0;// We want n to be equal to 0x11, that is, 17 In C, we usually use the following method to convert a string to an integer: [CPP] View plaincopyprint? Char * PTR = "123 "; Int n = 0; N = atoi (PTR ); Printf ("% d/N", N ); // Output: 123 Char * PTR = "123"; However, the ato

JS number converted to float, take n decimal: ========================================= The variables in JavaScript are weak types, all variables are declared Var, and are not as convenient as Java in the type conversion process, which is done by means of parseint (variables), parsefloat (variables), and so on. Note: There is no parsedouble (variable) for this type conversion, because in JavaScript there

one class file is another Id, to use the decimal point and control the digits of the decimal point, I use the following method: 1. When an attempt is created, round (avg (EXPSCORE) * 1000)/1000 as avg is used to control the number of decimal places; 2. Modify the attributes in the generated ***. hbm. xml file, for exa

Double temp=3.1415926;F Fixed point:string str1=temp.tostring ("F1");//Keep one decimal rounding Result: 3.1F Fixed point:string str2=temp.tostring ("F2");//reserved Two decimal places, rounding the following analogy results: 3.14N Number:string str2=temp.tostring ("N");//retention Result: 3.14(G) General (Default): String Str2=temp.tostring ("G");//retention Result: 3.1415926P Percent:string str2=temp.tost

Round Returns a numeric expression rounded to the specified length or precision. The displayed page requires that only four digits after the decimal point be retained. It is found that the number after the four decimal places can be truncated in the round (expression, 4, 1 ).If (round, 4) is written, it indicates rounding the four digits after the

Today, I found Baidu and Mu. I checked Google and Mu. I asked my friend and told me that I had done it myself and finally got it. Haha Everyone has noticed that, in fact, our law knows that it is wrong: Note: The function used to retain two decimal places in Javascript is tofixed (2) However, when this function is combined with the "%" sign, it will be confused and will not be heard. Please refer to the following example for comparison: Example 1

The division result of El expression is float.For example, $ {8/7}, $ {6/7}, and $ {12/7} are displayed on the page as follows:1.14285714285714280.85714285714285711.7142857142857142 Now, my goal is to only take the preceding integer. Now I use the The result is 1.Maxfractiondigits = "0" indicates to retain 0 decimal places, that is, to take an integer. Note: The integer is rounded to the nearest integer.If the result of $ {1/7} is 0 and the result of

Copy Code code as follows: The format of the amount s is the parameter to be formatted (floating-point type), n is the number of digits reserved after the decimal point function Formatmoney (s,n) { n = n>0 ns = parsefloat ((s+ "").

I saw several questions in a forum yesterday. One of them is to convert the decimal string to a number. I can see many people reply with the words "too simple !". After reading the replies from these people, I was wondering, is it really that simple? If exception handling is not required, it is indeed not difficult; If exception handling is required, it is difficult to fully consider the exception. To fully
