[quote user="jfizzle"]I do not find anything defined as Characteristic Presentation Format Descriptor.[/quote]

It's in ble_types.h. In ble_types.h it's defined as

#define BLE_UUID_DESCRIPTOR_CHAR_PRESENTATION_FORMAT  0x2904 /**< Characteristic Presentation Format Descriptor. */

I am reviewing the Nordic doc at:

https://github.com/adafruit/Adafruit_nRF52_Arduino/blob/master/cores/nRF5/nordic/softdevice/s132_nrf52_6.1.1_API/include/ble_gap.h#L262

I do not find anything defined as Characteristic Presentation Format Descriptor. Is there a different Nordic document that may describe haw that would be used with the nRf52380?

It should be possible. In the BLE spec it says that the format field of the descriptor should be set to 20 or 21 for 32- or 64-bit floating point respectively.
