Convert int array to float array

Boonie · **Author**

Is there a way to convert an into array to a float array.

This is the current way I am doing it:

Code:

size[0] = float(isize[0]);
size[1] = float(isize[1]);
size[2] = float(isize[2]);

No not really. you could make it easier on yourself and just loop through the elements.

PHP Code:


			
for (int i = 0; i < sizeof(someFloatArray); i++) {
    someFloatArray[i] = float(someIntArray[i]);
}

Code:

sizeof(someFloatArray)

Seems a little performance heavy lol.

Why would sizeof be performance heavy?

Isn't sizeof evaluated at compile time?

Just a little thing ddhoward; you wrote:

Code:

int < sizeof(someFloatArray)

sizeof is a evaluated at compile-time, it has no performance impact. But still unsure if that was sarcasm.

Why not create yourself a function to do it if you can't stand writing 3 lines each time? You know, code reusability, that's why they exist.
