Italic Angle in the Font Info Key Dimmensions: Positive or Negative value?

I'm making some macros that make use of the italic angle font info data.
While testing the macro, I've found that some fonts use a negative value.
For example, if the angle is 12°, some fonts use the value: 12 (positive) while some other use the value: -12 (negative)
Is there any reason to use a negative value?
Is it documented somewhere?
Thanks in advance

according to the spec, a positive value would be reserved for a "backslanted" font:

Thanks Jason.
It seems that the negative value is the correct one.
Weird logic....0 -
