 ### Interval arithmetic
 - Two methods for interval rounding are available:
- (i) narrow/slow (which uses hardward rounding mode changes for `Float64` intervals, and (ii) wide/fast (which does not change the rounding mode)
+ (i) narrow/slow (which uses hardware rounding mode changes for `Float64` intervals, and (ii) wide/fast (which does not change the rounding mode)
 - The current interval precision and rounding mode are stored in the `parameters` object
 - The macro `@interval` generates intervals based on the current interval precision
 - Trigonometric functions are "nearly" rigorous (for `Float64` intervals, correct rounding is not currently guaranteed)
