The parseFloat function converts its first argument to a string, parses that string as a decimal number literal, then returns a number or NaN .
Converting Integers to FloatsBy using the float() function, we can convert integers to floats.
So, when you assign an int value to float variable, the conversion of int to float automatically happens in Java. This is also called widening casting or widening primitive conversion. So, to convert an in to float using widening casting, you can just assign a value of int to float.
The parseFloat() function is used to accept the string and convert it into a floating-point number. If the string does not contain a numeral value or If the first character of the string is not a Number then it returns NaN i.e, not a number.
JavaScript only has a Number type that stores floating point values.
There is no int.
Edit:
If you want to format the number as a string with two digits after the decimal point use:
(4).toFixed(2) toFixed() method formats a number using fixed-point notation. Read MDN Web Docs for full reference.
var fval = 4; console.log(fval.toFixed(2)); // prints 4.00 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
