Convert Variable From Int To Float In Dart

In programming, variable type conversion is a common requirement. This article will focus on how to convert a variable from int to float in Dart, along with a detailed explanation of the relevant steps.

Code snippet for Variable Conversion

Here’s the necessary code to fulfil this task:

void main() { 
   int number = 6; 
   double doubleNumber = number.toDouble();
   print(doubleNumber);
}

After running this code, the output will be: 6.0

Code Explanation for Variable Conversion

This code’s primary purpose is using the toDouble() method to convert an int to a double. Since Dart does not support the data type float, the double data type is used for the floating-point numbers. When you need to convert an int to a float in Dart, this method comes in handy.

In the first line, an int variable called number is defined with the value 6.

   int number = 6; 

In the next line, the method toDouble() is applied to the number variable and the resulting value is stored in a new variable doubleNumber. The toDouble() method converts an int to a double.

   double doubleNumber = number.toDouble();

The third line allows us to output the result, which is 6.0. It shows that the int variable has been successfully converted into a double or float variable.

   print(doubleNumber);

Important to remember that using the toDouble() method does not modify the original int value but returns a new double value. Therefore, the original int variable, in this case number, remains unaltered.
