Having trouble with Signed and Unsigned INT type conversions

[Tom-H-PIC]

This is what I have that works correct.

Int Nset;
Float Nor_f

Nset = 10;
Nor_f = Nset/.0001174;

Nor_f now = 85178.875

This is all fine and what I expected!

But I need to change Nset to a sign int so that if I decrement Nset I can test for <= zero.

Signed Int Nset;
Float Nor_f

Nset = 10;
Nor_f = Nset/.0001174;

Nor_f now = 5.1265171797906E-32

There must be some thing about type conversions / promotions that I don’t understand.
If I type cast Nset in to a float then it works just fine.
But I though with the constant being a float that the complier would promote Nset to a float automatically?


Signed Int Nset;
Float Nor_f

Nset = 10;
Nor_f = (float)Nset/.0001174;

Nor_f now = 85178.875

Can someone give me insight me on this?

Thank All

The rule with CCS is, if it doesn't work, then type cast it.

(ie., Do whatever you have to do, to make it work).

I agree with PCM Programmer whole-heartedly!
