float point in interrups

Is float point permited in interrups ? Were I can find recomendations on float point in interrupts for RV compiler and lpc21xx target ?

There are no limitiations in using Floating arithmetic in interrupts.

But what about

__irq Enables a C or C++ function to be used as an interrupt routine called by
the IRQ or FIQ vectors. All corrupted registers except floating-point
registers are preserved, not only those that are normally preserved under
the AAPCS. The default AAPCS mode must be used.

Wow, now I know, I know:

...Exept default stack configuration for Interrupt mode 0x0000 0080
