All of the tricks in the other answers (e.g. unary plus) involve implicitly coercing the type of the string to a number. You can also do the same thing explicitly with the Number function. Parsing Convert Float to Int Using Number.toFixed() in JavaScript. Number.toFixed() behaves a bit differently from the parseInt(). It rounds off the number to the nearest integer value. Hence, beware of the rounding fact. Number.toFixed() rounds of the decimal value of float less than .5 to the lower integer value.
