Dividing a 32bit floating number into (4) 8-bit integers for

[liche]

I have a few 32bit floating numbers which I want to use to send to an EEPROM for storage. Does anyone have an idea of how to break this 32bit floating number into 4 separate 8-bit integers???

The make8() function only works on integers and does work with floating point numbers.

Thanks

See CCS FAQ "How do I write variables to EEPROM that are not a byte?" That example is about saving floats.

Here's the answer to your question:

Personally, I prefer the unions:

union Convert
{
float f;
int8 i[4];
};

union Convert C;
C.f=some_float_value;
write_eeprom(address,i[0] ) ;
write_eeprom(address+1,i[1] ) ;
write_eeprom(address+2,i[2] ) ;
write_eeprom(address+3,i[3] ) ;


I hope that answers your question.
