To extract the decimal value from a float in Android Studio, you can use the float
data type's remainder()
method. This method returns the remainder of the division of one float by another.
Here's an example of how to extract the decimal value from a float in Android Studio:
float value = 3.14159f; float integerPart = (int) value; float decimalPart = value - integerPart; System.out.println("Integer part: " + integerPart); System.out.println("Decimal part: " + decimalPart);Socrue:www.lautturi.com
In the above example, the integerPart
variable is assigned the integer value of value
by casting it to int
. The decimalPart
variable is calculated by subtracting the integerPart
from value
.
This method works because the remainder of the division of a float by an integer is the decimal part of the float.
Alternatively, you can use the DecimalFormat
class to format the float and extract the decimal value as a string. Here's an example of how to use the DecimalFormat
class to extract the decimal value from a float:
float value = 3.14159f; DecimalFormat df = new DecimalFormat("#.#####"); String decimalString = df.format(value); float decimalPart = Float.parseFloat(decimalString); System.out.println("Decimal part: " + decimalPart);
In the above example, the DecimalFormat
object is used to format the value
float as a string with a specific number of decimal places. The parseFloat()
method is then used to convert the string back to a float. This method allows you to control the number of decimal places in the decimal part of the float.
