How do I convert types in Julia?

In Julia, you can convert types using the convert function or by using constructors. For example, convert(Int, 3.5) will convert the float 3.5 to an integer.

Can you give me an example of converting a string to an integer?

Sure! You can use the parse function for that. For example, parse(Int, "123") will convert the string "123" to the integer 123.

What happens if the string cannot be converted?

If the string cannot be converted, Julia will throw a ArgumentError. For instance, parse(Int, "abc") will result in an error.

Are there other ways to handle type conversion errors?

Yes, you can use a try-catch block to handle errors gracefully. For example:

try
    parse(Int, "abc")
catch e
    println("Error: ", e)
end
