What is double?
PostPosted: Sun Jan 22, 2023 11:17 pm     Reply with quote
In the ide the double is in blue (defined), it compiles but in printf it outputs garbage. According to help double is undefined. Is it defined or not, and what does it convert to?

This depends on the chip involved.

In the standard PIC12/16/18 compiler the manual says:
Quote:

double - A reserved word but is not a supported data type.

It is reserved, because it exists when using the PIC24/30/33.

Normally if you declare a variable as 'double', it will be generated as
a standard float32. Normally it works as such. How are you trying to
print this?. A quick test shows it merrily working with %f to print.
