idl programming language - Scrambling an array in idl -

i wondering if there module in idl 1 can utilize scramble array of floating point numbers. tried using scramble.pro problem returns integers, , if seek utilize float doesn't homecoming exact numbers entered, example:

array = [2.3, 4.5, 5.7,8.9] scr_array = scramble(array) print, scr_array output: 4 2 8 5

and if utilize float:

print, float(scr_array)

the output is:

4.0000 2.0000 8.0000 5.0000

any ideas?

try using this sampling routine, asking elements:

idl> array = [2.3, 4.5, 5.7,8.9] idl> scramble_indices = mg_sample(4, 4) idl> print, scramble_indices 1 3 0 2 idl> print, array[scramble_indices] 4.50000 8.90000 2.30000 5.70000
