[CM] problem with doubles and SC

[nik gaffney]

hi,

you might want to check the typetag sent with the message, since doubles are not 
  'standard' osc datatypes, this might be a problem.

if you dont need 64bits, coerce to a single first. if you do really need 64bit 
precision in supercollider, then its probably acceptable to output correctly 
encoded 64bit floats, with the typetag 'd'.
