an alternate solution using command line utilities tr , fold

$ tr '\n' ' ' < file | fold -w24  -6.222  -5.809  43.663   3.778  -5.809  43.663   7.784   5.483 -14.013   6.873   5.197 -13.865   5.648  -0.107 -14.156   5.485  -1.058 -14.103  -0.809   7.565 -11.708  -1.157   6.740 -11.343  -0.687  -7.913 -15.833  -0.823  -8.865 -15.733
