Method

double readFloatFromString(String inStr)
Read float data from a string

DecimalFormat dformat = new DecimalFormat("#");
DecimalFormatSymbols dfs = new DecimalFormatSymbols();
dfs.setDecimalSeparator('.');
dformat.setDecimalFormatSymbols(dfs);
String trimStr = inStr.trim();
if (trimStr.startsWith("+")) {
 trimStr = trimStr.substring(1);
ParsePosition pp = new ParsePosition(0);
Number num = dformat.parse(trimStr, pp);
if (null == num) {
 throw new Exception("Invalid Float In TLE");
return num.doubleValue();

Float string2float(String arg, Locale loc)

if (arg == null) {
 return null;
NumberFormat nf = NumberFormat.getInstance(loc);
return nf.parse(arg).floatValue();

Object tryParseFloat(String floatValue)
try Parse Float

Object parsedValue;
try {
 parsedValue = Float.parseFloat(floatValue);
} catch (NumberFormatException nfe) {
 parsedValue = floatValue;
return parsedValue;
