Re : 回复： Re: use array to store negative number

[hengfo]

Hi,

   I use "Initialize array" to set all the 500 elements to "0". Then I input numbers to  "Replace Array Subset"  and generate a new array. But all the positive numbers are correct, negative numbers just become "0". Why? How can I store the negative number in this array?

   Thank you in advance!

Hi,
what data type (numeric representation) are you using for the array elements? If it is integer, make sure it's not unsigned (U8, U16, ...) as this data type doesn't allow negative numbers.
Hope this helps

Thank you! But how to set the data type of array elements?

Right click on array, then REPRESENTATION, Then DBL
