Method Details

floorMod
public static long floorMod(long x, long y)Backport of floorMod from the JDK since we need to support 1.6. Returns the largest (closest to positive infinity)long
value that is less than or equal to the algebraic quotient. There is one special case, if the dividend is the Long.MIN_VALUE and the divisor is1
, then integer overflow occurs and the result is equal to theLong.MIN_VALUE
.Normal integer division operates under the round to zero rounding mode (truncation). This operation instead acts under the round toward negative infinity (floor) rounding mode. The floor rounding mode gives different results than truncation when the exact result is negative.
 Parameters:
x
 the dividendy
 the divisor Returns:
 the largest (closest to positive infinity)
long
value that is less than or equal to the algebraic quotient.  Throws:
ArithmeticException
 if the divisory
is zero
