How to round off a float value if the value is like:
eg:
but if the value is like:
1.2 ==> then it should return 1.2
1.90 ==>then it should return 1.9
I have tried to round off it and also tries different solutions but that doesn't worked for me.
You can create a helper function like this
static public void Normalize(String pattern, double value ) {
DecimalFormat formatter = new DecimalFormat(pattern);
String normalizedValue = formatter.format(value);
System.out.println(normalizedValue);
}
Normalize("0.#####",2.40); // 2.4
Normalize("0.#####",2.0); // 2
This worked for me.
What you're talking about here is a display issue. The "0" in the 1.0 shows how accurate the number is, if you are only displaying 1 then the person reading does not know how accurate that value is (compared with 1.1, 1.9 or even 1.0003).
My suggestion would be to convert your answer to a string and check if the last value is "0", and if so remove it for display purposes (or some other formatting solution).
Note: I wouldn't recommend doing this because it changes the meaning of the value.
