Math.Round (x*100)/100, of course I want Math.Round (x*100), it doesn't matter. But the direct use of Math.Round (x*100) There is a problem, sometimes there will be a small error, showing a lot of bits, such as 0.9996*100, will become 99.960000000000

For example: 12345 format to 12,345.00 12345.6 format to 12,345.60 12345.67 format to 12,345.67 Leave only two decimal places. When I came back, I wrote a format function. You can control the number of decimal places and automatically rounding. The

Copy Code code as follows: Amount Format Conversion function Parseprice (s) { var n = 2//Set number of decimal places reserved s = parsefloat ((s + ""). Replace (/[^\d\.-]/g, "")). ToFixed (n) + ""; var L = s.split (".") [0].split ("").

I ran into a problem today when I wrote the program. about how to control floating-point numbers only two digits after the decimal point, the normal idea is to use the round function, such as round (A, 2), but in the face of the following problems

#include #include Double Conv (char *string){Double ch[10];int i = 0,j =0, count = 0;Double num = 0;while (* (string+j)!= ' "){Switch (* (STRING+J)){Case ' A ':CH[J] = 10;BreakCase ' B ':CH[J] = 11;BreakCase ' C ':CH[J] = 12;BreakCase ' D ':CH[J] = 1
