Does the "Avoid using floating-point" rule of thumb apply to MCUa microcontroller with Floating Point Unita floating point unit (FPU)?

As a rule of thumbsthumb, I try to avoid using floating-point in my embedded system codebase.
Floating

Floating-point variables are:

  • Computation-intensive
  • Not atomic (can cause problems in an RTOS application or with interrupts)
  • Their precision can cause non-obvious behaviour (float comparison problem).

But what about a microcontroller with a Floatingfloating point unit (like the STM32F4)?

Do those concerns still apply? Would you still advise against using floating-point?
