How to Convert a Set of Strings to a Set of Floats in Perl - Step by Step Examples

How to Convert a Set of Strings to a Set of Floats in Perl ?

To convert a set of strings to a set of floats in Perl, you can use the map function to transform each string value into its float representation.

In this example,

First, we create an array of strings named @stringArray1 with values ("1.1", "2.2", "3.3").
Next, we use the map function on @stringArray1 to transform each string value into its corresponding float value. We pass a code block to map that converts each string value to a float using the += 0 operator.
We store the result of this transformation in a new array called @floatArray1.

@stringArray1 = ("1.1", "2.2", "3.3");
@floatArray1 = map { $_ += 0 } @stringArray1;
print join(", ", @floatArray1);

1.1, 2.2, 3.3

In this example,

First, we create an array of strings named @stringArray2 with values ("4.5", "5.6", "6.7").
Next, we use the map function on @stringArray2 to transform each string value into its corresponding float value. We pass a code block to map that converts each string value to a float using the += 0 operator.
We store the result of this transformation in a new array called @floatArray2.

@stringArray2 = ("4.5", "5.6", "6.7");
@floatArray2 = map { $_ += 0 } @stringArray2;
print join(", ", @floatArray2);

4.5, 5.6, 6.7
