JavaScript function Summary-The more effort, the luckier!

parsed number.DescriptionWhen the value of the parameter radix is 0, or if the parameter is not set, parseint () determines the cardinality of the number based on string.Example:If string starts with "0x", parseint () resolves the remainder of the string to a 16-binary integer.If string starts with 0, then ECMAScript V3 allows an implementation of parseint () to parse subsequent characters into octal or hexadecimal digits.If string starts with a number from 1 to 9, parseint () parses it into a

to determine equal to the expected value. The smallest value in JavaScript is Number.min_value, where it can be imagined that number is a class, and Min_value is a static variable that stores the minimum value, and the Number.MAX_VALUE is the largest. If the calculation exceeds this maximum and the minimum range, it will be automatically converted to the Infinity value, if it is a negative number, that is-infin
