How to convert String to Float in Kotlin - Step by Step Examples

How to convert String to Float in Kotlin ?

To convert a string to float in Kotlin, you can use the 'toFloat()' method of the String class.

In this example,

We create a string str1 with a value of "3.14".
We convert the string to a float using the toFloat() method and store the result in a variable float1.
Finally, we print the float value float1 to standard output.

fun main(args: Array<String>) {
    val str1 = "3.14";
    val float1 = str1.toFloat();
    println("Float value is: $float1");
}

Float value is: 3.14

In this example,

We create a string str2 with a value of "10.5".
We convert the string to a float using the toFloat() method and store the result in a variable float2.
Finally, we print the float value float2 to standard output.

fun main(args: Array<String>) {
    val str2 = "10.5";
    val float2 = str2.toFloat();
    println("Float value is: $float2");
}

Float value is: 10.5
