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

How to convert String to Float in Perl ?

To convert a string to a float in Perl, you can use the 'sprintf()' function.

In this example,

We create a string variable $str1 with a value of "3.14".
We use the sprintf() function to convert the string to a float and store the result in a variable $float1.
Finally, we print the float value $float1.

# Convert "3.14" String to Float
my $str1 = "3.14";
my $float1 = sprintf("%.2f", $str1);
print "Float value is: $float1\n";

Float value is: 3.14

In this example,

We create a string variable $str2 with a value of "10.5".
We use the sprintf() function to convert the string to a float and store the result in a variable $float2.
Finally, we print the float value $float2.

# Convert "10.5" String to Float
my $str2 = "10.5";
my $float2 = sprintf("%.2f", $str2);
print "Float value is: $float2\n";

Float value is: 10.50
