How to transfer the data of AFG 1022 to transmits a waveform to the edit memory1?

DATA:DATA EMEMory1,#42000<DAB><DAB>...<DAB>

Hello, 
I have no idea how to transfer the DBL data/floating data to above<DAB>, for example, if I want to transfer 3 points(3.141, 2.5, 3) to AFG1022,

DATA:DATA EMEMory1,#40003<DAB><DAB>...<DAB>      OR    DATA:DATA EMEMory1,#13<DAB><DAB>...<DAB> Should I write?

and what is the DAB values should I send for 3.141, 2.5, 3 . I'm trying to write the command in LabVIEW.

The data is transferred using arbitrary blocks, as defined in the IEEE 488.2 standard and page 6 of the programmer's manual.
