how to convert a double to boolean array

[PincoG]

Hi,
I'm looking a way to convert a double in a boolean array of 64 elements and viceversa.

Please test this example.

Good luck!

Well, I guess that your boolean variable shall be true above or below a certain specified value.
You can use the > or < function on the double array. The result should be the boolean array you are looking for.

The version posted by miguel doesn`t work properly on my machine.

Try this modified version. The problem was the coercion of the bouble (8 byte) to a U32 (4 byte) in the "number to boolean array" funtion.

maybe i didn't undertand your answer or you didn't undestand the question: only 1 double in an array of boolean...

[PincoG]

it doesn't work: the number to array works only for 32 bit!!!!

Thankyou: this maybe works but i founded something simpler, if You are ineterested, i'm working on this, to find a way to reverse it.

Well, I thought you are looking to process a threshold value fast, but as I have learned from the other postings you are looking for a method to convert a double value to a binary value (which is represented as a array of boolean).
Sorry for my misunderstandig!

You`re doing basically the very same as in my example. Granted, it looks simpler, but the operations are basically the same.

Also, my version has already incorporated a method to reverse the operation. Look carefully at my example, and you`ll see that the DBL is re-created from the boolean array.
