Convert Float to Int With Bitwise Operators in JavaScript Unlike the parseInt() function, string value conversion to float is not supported by Number.toFixed(). One can use this function to convert only float values.Unlike the parseInt() method, Number.toFixed() is not that famous for extracting the integer part, as it does a round-up of the float value passed as a parameter.For our purpose, we need not mention any argument as, by default, it takes the parameter to be 0, hence returning an integer value. Usually, we need to pass a parameter to this function that specifies the number of digits after the decimal in the output. The syntax for Number.toFixed() function is as follows. If the decimal value is 0.5 or greater, then the float number will be rounded off to the next higher integer value. Number.toFixed() rounds of the decimal value of float less than. It rounds off the number to the nearest integer value. Number.toFixed() behaves a bit differently from the parseInt(). Convert Float to Int Using Number.toFixed() in JavaScript

Hence, it is good to include an isNaN() check while converting values so that the code is safe and doesn’t break. parseInt() returns NaN in case conversion is not possible.While converting float values, parseInt() discards the decimals and doesn’t consider them while returning the whole number part of the float value.For more information, refer to the MSN docs.The following code shows the behavior of the function. In this section, we will see the conversion of a float number to an integer number. With this function, we can convert the values of different data types to the integer type. unc() Convert Float to Int Using the parseInt() Function in JavaScript.Using Math library functions in javascript.In JavaScript, we have many ways of converting float to int, as shown below.
