How about this:

IDL> str = strsplit(str, /extract)
IDL> str = replicate('1000 1000.1515 400 40', 10)
IDL> str = strsplit(str, /extract)
IDL> array = float(str.ToArray() )
IDL> help, array
ARRAY FLOAT = Array[10, 4]
IDL> print, array[*,0]
1000.00 1000.00 1000.00 1000.00 1000.00 1000.00 1000.00 1000.00 1000.00 1000.00

Cheers,
