How would I convert the C function gcvt() to VB.NET?

For example, it is something like this now:

gcvt(myDouble, 5, myString)

Where 5 is the number of digits, not necessarily the number of characters.

gcvt converts a double to string.  That is pretty simply in VB.NET:

Dim myDouble As Double = 5.234
Dim myString As String = myDouble.ToString("N3")

That's not quite the equivalent and is similar to what I was already doing. I might have to settle for that at the moment. Here's a google result for gcvt():

The ToString has many different formats, and if you are looking for the exact gvct, then you could do something like this:

   gcvt (1365.249,6,buffer);  ===> ToString("N2") or ToString("####.##")
