Use JavaScript to take float type two digits after the decimal point, example 22.127456 to 22.13, how to do? 1. This method is least recommended: function Get () { var s = 22.127456 + ""; var str = s.substring (0,s.indexof (".") + 3); alert (str); } 2. Use regular expressions to get: function Get () { var a = ' 23.456322 '; var anew; var re =/([0-9]+\.[ 0-9]{2}) [0-9]*/; anew = A.replace (Re, "$"); alert (anew); } 3. More ad

When two integers are divided, because the number after the decimal point is truncated, so that the result of the operation is an integer, so if you want to get the result of the operation is the expected floating-point number, then the two integers must be one or all cast as floating-point numbers.For example:(float) A/b cast one of the integers to a floating-point number, and then divide by another integerA/(float) b(float) A/(float) b//convert two
