ruby is converting octal/hex numbers into integers.. so it should be fine.. but it's not easy to test through rspec..

```ruby
irb(main):006:0> 0x2A
=> 42
irb(main):007:0> 0x2A.to_f
=> 42.0
irb(main):008:0> 0x2A.class
=> Fixnum
irb(main):010:0> 0x2A.is_a? Numeric
=> true

irb(main):014:0* 025
=> 21
irb(main):015:0> 025.to_f
=> 21.0
irb(main):016:0> 025.class
=> Fixnum
irb(main):017:0> 025.is_a? Numeric
=> true
```
