Float numbers in Groovy are represented by the keyword float, and they are used to represent decimal values. Here are some examples of how to use float numbers in Groovy:
Example 1: Simple float variable declaration and initialization:
float height = 6.2f
Example 2: Arithmetic operations using float variables:
float length = 10.5f
float width = 5.4f
float area = length * width
Example 3: Type conversion from other data types to float:
def integerNumber = 5
float floatNumber = integerNumber as float
Example 4: String to float conversion:
String str = "2.4"
float floatNumber = Float.parseFloat(str)
In general, you can perform all arithmetic operations on float numbers, and you can mix them with other numeric data types such as int and double.
