| isdigit unexpected behavior |

I'm parsing a string separated by commas and some data is a float number but I don't need the decimal part so I'm filtering by using isdigit(x) function but that function return true when is a dot(.) and in the CCS help says:
isdigit(x) X is '0'..'9'
So there's any way to specify that only returns true to 0 to 9 ASCII codes?

Never mind, my mistake, bad pointer.
| Code: | Dummy=(*Punt_GGA[8]+x);
if(isdigit(Dummy)) |
Corrected.
| Code: | Dummy=(*(Punt_GGA[8]+x));
if(isdigit(Dummy)) |

Yes. Use 'isamong'.
The 'isamong' command is the 'parent' of the others.
So:
| Code: |
#define isdigitonly(x) isamong(x, "0123456789")
|
will give you a new operation 'isdigitonly', that behaves exactly like 'isdigit', except is only accepts the digit not the decimal.
isdigit, itself is only a similar macro expansion declared in ctype.h |
