The following value gives me wrong precision. It is observed with only specific numbers. It might be a floating representation problem, but wanted to know the specific reason.
String m = "154572.49"; //"154,572.49";
Float f = Float.parseFloat(m);
System.out.println(f);
The output it is printing is 154572.48 instead of 154572.49.
If you want decimal numbers to come out as exactly as you entered them in Java, use BigDecimal instead of float.
Floating point numbers are inherently inaccurate for decimals because many numbers that terminate in decimal (e.g. 0.1) are recurring numbers in binary and floating point numbers are stored as a binary representation.
