 - Many useful geometric functions (e.g. dot product, cross product, vector reflection etc)
 - 32-bit scalar operations (e.g. sin32, cos32, equality using epsilon, sqrt32 etc)
 - Useful 32-bit constants (e.g. pi, Deg2Rad, Rad2Deg, float32 epsilon etc)
-- Simple 'siwzzle' interfaces that allow you to do things like `.X()` or `.R()` etc.
+- Simple 'swizzle' interfaces that allow you to do things like `.X()` or `.R()` etc.
 - Very easy to use with graphics/native APIs as everything is implemented using arrays
-- `.String()` functions on all types for pretty pritning
