returning float union

[alexz]

I have got a definition of the following union:
extern union unionFloat
{
float fl;
unsigned char cha[4];
};
extern union unionFloat AvStepsPerMm;
extern union unionFloat AvStepsPerMm_inv;

Then I have got a function:

unsigned float getAvStepsPerMm(void)
{
uchar i;

for (i=0;i<4;i++)
{
if ((AvStepPerMm.cha[i] ^ AvStepPerMm_inv.cha[i]) != 0xFF)
{
systemAlarm(CRITICAL_FLOAT_FAILURE);
while(1);
}
}

return(AvStepsPerMm.fl);
}

I call it here:

readSFlash(0x04, (uchar*)&verify.fl);
if (getAvStepsPerMm() != verify.fl)
{}

I have got the following errors on the "if" statement:
Error [1128] compatible scalar operands required for comparison
Error [1122] scalar operand expected for '!' operator
Error [1117] scalar type expected in 'if' statement

Try declaring

Are you using the CCS compiler? I get an error if I try unsigned but otherwise it compiles just fine.

Okay, how do you expect people to help when they assume that you are using CCS compiler!?!?! Why are you asking these questions on the Microchip forum? Good luck and maybe someone else will waste time helping ya, I ain't
