Definition and usage of the parsefloat () method: The Parsefloat () method can parse a string and return a floating-point number. Note: This method returns Nan if the first character in the string cannot be converted to a number. If a string

First, parseint ()The parseint () method first looks at the character at position 0, determines if it is a valid number, and if not, the method returns Nan, and no further action is taken. However, if the character is a valid number, the method will

Today, we used parseFloat (the first parameter, 10) in jquery. We didn't know what the second parameter meant. So I checked it online and wrote it down if I forgot it later.Definition and usage: The parseFloat () function parses a string and returns
