The
java.math.BigDecimal.byteValueExact() is an in-built function which converts the BigDecimal to a byte and checks for lost information. Any BigDecimal value
greater than 127 or less than -128, will generate an exception as it doesn't fit in byte range.
Syntax:
public byte byteValueExact()
Parameters: The method does not accept any parameters.
Return Value:This method returns the byte value of the BigDecimal Object.
Exception: This function throws
ArithmeticException in case if the BigDecimal has a nonzero fractional part, i.e., in case of a decimal values, or is out of the possible range for a byte result.
Examples:
Input : 127
Output : 127
Input : -67
Output : -67
