Get the maximum allowed value of the Double data type

[vpellerito]

I'm trying to set the value for my array to the maximum value allowed for a Double data type. How do I do this without explicitly setting a constant (which I can't seem to do anyway)?
I've seen this as a property in some languages but not sure how it works in VB.
Thanks

Hi vp,

I'm not clear on your intention.
Why on earth would you want to set the size to 3 (followed by 300 zeros)?

a) I'm not sure if this would exceed memory limitations
b) I'm not sure if this would automatically reserve said memory every time the app. was executed. (What a waste at the start - with very little data in there).

Seems a bit overkill to me. You should declare an array and redim it when necessary, not declare it at the max to start with.

Thanks for your responses. Sorry for my late response but I was away this weekend.

The reason why I asked how to set an array value to the maximum value allowed for a Double data type was because this was what was done the original author of the code.
I want to take some code written in Fortran and convert it to VB. It's an algorithm for Jenk's optimization method and the code initialized a matrix that way. See here for the code in Fortran

and here in PHP

To be honest, I'm not entirely sure why the array needs to be initialized as such. I don't have access to the original paper explaining the algorithm. The irony of all this is that the algorithm was probably originally written in Basic.

VP,

In that case, there IS no reason to define it to the maximum.

As BOb as said:

Use REDIM PRESERVE ArrayName("current size" + 1)

Every time you come to add a new element.

N.B. You MUST use PRESERVE, otherwise REDIM alone will wipe the original array content.
