convert double* to float*

[Gregosky]

Hi guys,

I have written a library that manipulates data stored in double arrays. It took months to fine tune it and here it is, working fine. Everything was great until I started integrating my project with another open source project that uses float arrays. I need to pass my double arrays to the function that requires float arrays.. I am out of ideas how to do that.. I would like to avoid re-writing my project to use float instead of double and I also would like to avoid copying values from double array to float array and pass float array.
So here is the question - is there any way to pass my double array to function that requires float array?

Cheers,
Greg

Ok. It is not possible, I will copy double array to float array and do conversion here.

Thanks anyway,
Greg

It's not possibe to copy a double to a float without potentially losing data. This will produce a compiler warning.

Your solution here is to rewrte your library to use double instead of float. That's because a float can always be copied to a double.

float is an obsolete type. A remnant from the days of computers with very tiny memories. Today, unless you can write down on paper a technical reason why you need a float, then use a double.

I meant that I will copy double array to float array element by element accepting loss of precision :-) That solution works fine.
Thx anyway.

Accepting a loss of precision draws a compiler warning. Mainstream software sets warnings to errors before release. Therefore, in the real world your code would not compile.

Try to code in such a way as to not have warnings.
