[...result][0]; return parseInt(groups[1] + groups[2] + groups[3]);}console.log(convertVersionToNumber("# 1.03.00")); 因为您使用的是regex,即/^# ([0-9]).([0-9][0-9]).([0-9][0-9])\s*/ 2) 如果有多个匹配项,那么yon可以将结果分散在一个数组中,然后使用for..of循环匹配...

format(1.23) '1.2300e+00' In these examples, you use different precision values to display the output number. The precision is separated from the width by a literal dot (.). For string representation types, precision specifies the maximum width of the output: Python 👇 >>> f"{'...
You may already be familiar with how to convert a string containing an integer to a number using int(), which is especially useful when working with user input. For example, the following converts the string "25" to the integer 25:
Over the following sections, we will explore four different methods you can utilize to convert your number to a string. For most cases, you will want to use the “str()” function. However, it is always helpful to know other ways of dealing with simple tasks. ...
the result will also be a Unicode object.If format requires a single argument, values may be a single non-tuple object. [4] Otherwise, values must be a tuple with exactly the number of items specified by the format string, or a single mapping object (for example, a dictionary...
strings. This conversion involves working with configuration files, data storage, and serialization. When dealing with user input, you frequently get data in string format. For user validation, mathematical calculations, and data processing tasks, you must convert string input to integers and vice ...
