fstorage read a int or float from flash

Goodday

I have integrated the fstorage peripheral  example with the BLE_beaconing example. SDK 15.2. I can read and write strings. I cannot read back the hex number if declared as an int or a float

my problem lies in how to use this function to read a float or int.

rc = nrf_fstorage_read(&fstorage, 0x3e100, &m_data_read,sizeof(m_data_read));
