Saving a float-value in extern eeprom

[XorpiZ]

Hi.

Just a quick question. I want to use write_ext_eeprom to write to an external eeprom (24LC512), but I was wondering whether it is possible to give the function a float as the second parameter?

ie: write_ext_eeprom( address, float_value)?

Or do i have to convert my float_value to a hex_value first? And if so, how do I do that?

Microchip & CCS use 32 bit format to handle/store a float. Those 4 data bytes must
be in 4 consecutive mem positions/addresses.

The exponential notation is arranged as follows:
1) The first 8 bit (MSB) represent the exponent.
2) The next single bit keep the sign
3) The following 23 last bits represent the mantisa.

Silly me.. *note to self* Read the FAQ next time.

WRITE_FLOAT_EXT_EEPROM(long int n, float data) {
int i;

for (i = 0; i < 4; i++)
write_ext_eeprom(i + n, *(&data + i) ) ;
