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

How to convert String to Float in Ruby ?

To convert a string to a float in Ruby, you can use the 'to_f' method.

In this example,

We create a string variable str1 with a value of "3.14".
We use the to_f method 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
str1 = "3.14"
float1 = str1.to_f
puts "Float value is: #{float1}"

Float value is: 3.14

In this example,

We create a string variable str2 with a value of "10.5".
We use the to_f method 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
str2 = "10.5"
float2 = str2.to_f
puts "Float value is: #{float2}"

Float value is: 10.5
