The problem of formatting the floating-point number, using Format (col,2) to retain the two-bit decimal point, there is a problem, such as the following statement, after we give a workaroundSELECT FORMAT (12562.6655,2);Results: 12,562.67View

The simplest use:float i=1.6667f;String Show=i.tostring ("0.00"); Result 1.67 (rounded)Other similar methods:String Show=i.tostring ("F");//"F2", "F" is case insensitiveString Show=string.format ("{0:f}", i);//can also be F2, or "{0:0.00}Float

JS limit the amount of textbox two digits after decimal point String.prototype.count = function(c){var sum = 0;for(var i = 0;i = 96 && event.keyCode = 48 && event.keyCode 0 && isDot){return false;} if (v.indexOf('.') != -1 && event.keyCode !

The function that is rounded in JS is toFixed (n), and N is the number of decimal digits to keep. N is 0~20, and when N exceeds 20, JS will go wrong.If it is 0 o'clock before the decimal point and the previous one to be intercepted, it is not

We can see that many people want to retain the decimal point after the number, but most of them write a function to intercept the number, and consider rounding it down. It is quite complicated to write it. In fact, the javascript Number object has a

In C + + programming, sometimes ask us to keep the data after the decimal point, or how many digits to retain the number of valid numbers and so on, then we need to use the setiosflags and setprecision functions, remember to include the header file #
