I have a file whose contents look like this.
2,0,-1.8433679676403103,0.001474487996447893 3,1,0.873903837905657,0.6927701848899038 1,1,-1.700947426133768,1.5546514434152598
CSV with four columns whose third and last columns are floats.
I want to get rid of the whole part of the numbers (including the sign) and keep only the three first digits of the decimal part so that the above sample would become
2,0,843,001 3,1,873,692 1,1,700,554
How can I do this?
