converting to ints

[Joe Van Dyk]

Hi,

I have a class that could look something like this

class MyClass
attr_accessor :x, :y, :z

def math(a, b, c)
end
end

I want to be able to pass in strings to this class and have everything
converted to fixnums (or floats). Do I need to manually do the
setters for x, y, and z and convert a, b, c?

Yes.

Yes.

Wondering if it would be useful to have functions like
attr_accessor_int :a_int, :another_int
attr_accessor_string :a_string=20

and then dynamically create the following methods

def a_int=3D(x); @a_int =3D x.to_int; end
def another_int=3D(x); @another_int =3D x.to_int; end
def a_string=3D(x); @a_string =3D x.to_s; end;

and then dynamically create the following methods

def a_int=(x); @a_int = x.to_int; end
def another_int=(x); @another_int = x.to_int; end
def a_string=(x); @a_string = x.to_s; end;

You might want to use #to_i rather than #to_int, so that strings are
converted. Or maybe not, depending on what you want...

irb(main):001:0> "1".to_int
NoMethodError: undefined method `to_int' for "1":String
from (irb):1
irb(main):002:0> "1".to_i
=> 1

Yes, you're right. Brain fart on my part.
