Does anyone know off hand if defining this and enabling floating point has any
Does anyone know off hand if defining this and enabling floating point has any
negative side effects if you don't need it? Size? Optimization? Other? That
is my only concern for enabling in all modules which is why the initial
proposal was for a new library.

used in mu_plus (the Microsoft UEFI value add to EDK2) by the OnScreenKeyboard
driver as well as the UiToolKit driver. If you happen to use
