you could read this CPLEX technote :

http://www-01.ibm.com/support/docview.wss?uid=swg21615825

I gave the example

float f = sqrt(2);
execute {
function formatFloat_prec8 (f) {
f = Math.round(f*100000000);
var fs = f.toString();
fs = fs.substring(0,fs.length-8)+','+fs.substring(fs.length-8,fs.length);
return fs;
}
writeln(formatFloat_prec8(f));
};

which gives

1,41421356
