formatted fprint() is usually the tool:
BUT.......
show your code - especially what you are trying to compile
and what you want to achieve |

After reading about the advantages of using variables of type fixed decimal point over using variables of type float tried to declare as an example: int16 _fixed (2) money;
| Code: |
#include <16F873A.h>
#device adc=8
#fuses hs
#fuses nowdt
#fuses nolvp
#fuses noput
#use delay(clock=20000000)
void main(void)
{
int16 one;
int16 two;
int16 _fixed(2) money;
money=1.23;
money+=3;
}
|
When I compile the program:
Clean: Deleting intermediary and output files.
Clean: Deleted file "extreme_potencia_7seg.ESYM".
Clean Warning: File "C:\Next Controladores\Next Extreme\software\extreme_potencia_7seg.o" doesn't exist.

| I'm not using this new-fashioned stuff, but it seems like _fixed(n) has been broken in CCS V4.133 or V4.134. Ask CCS. |

Thank you for your attention.
The problem is that I am using the demo version and I have no right to support. |

You can still report the issue to CCS. Given they want to sell you the compiler, they should still react.

Thank you.
I did the same test on version 4.130 and it worked.
Now it's wait if this type of data no longer exists or is a version 4.135 bug and will be fixed.
Best Regards. |

Why not work in integer cents (or UK pence) when calculating with money?

as wisely mentioned above- if int16 money is unitary cents , then
printf("%5.2w ",money);
will format as you wish, since you are not going to be able to use fixed point integers for calculation anyway, are you ?? |
