### Question:
FloatOperations implements MathOperations<Float>, Comparator<Float> { public Float roundUp( Float value, int decimalShift ) { if (value == 0) return 0.0f; double shiftedValue = (Math.abs(value.doubleValue()) * Math.pow(10.0d, decimalShift) + 0.5d) * Math.signum(value); double roundedValue = (long)shiftedValue; return (float)(roundedValue * Math.pow(10.0d, -decimalShift)); }  Class<Float> getOperandClass(); Float add( Float value1,
                      Float value2 ); Float subtract( Float value1,
                           Float value2 ); Float multiply( Float value1,
                           Float value2 ); double divide( Float value1,
                          Float value2 ); Float negate( Float value ); Float increment( Float value ); Float maximum( Float value1,
                          Float value2 ); Float minimum( Float value1,
                          Float value2 ); int compare( Float value1,
                        Float value2 ); BigDecimal asBigDecimal( Float value ); Float fromBigDecimal( BigDecimal value ); Float createZeroValue(); Float create( int value ); Float create( long value ); Float create( double value ); double sqrt( Float value ); Comparator<Float> getComparator(); Float random( Float minimum,
                         Float maximum,
                         Random rng ); double doubleValue( Float value ); float floatValue( Float value ); int intValue( Float value ); long longValue( Float value ); short shortValue( Float value ); int getExponentInScientificNotation( Float value ); Float roundUp( Float value,
                          int decimalShift ); Float roundDown( Float value,
                            int decimalShift ); Float keepSignificantFigures( Float value,
                                         int numSigFigs );  }### Answer:
@Test public void shouldRoundNumbersGreaterThan10() { assertEquals(101.0f, ops.roundUp(101.2523f, 0), 0.01f); assertEquals(101.0f, ops.roundUp(101.2323f, 0), 0.01f); assertEquals(101.3f, ops.roundUp(101.2523f, 1), 0.01f); assertEquals(101.2f, ops.roundUp(101.2323f, 1), 0.01f); assertEquals(110.0f, ops.roundUp(109.2323f, -1), 1f); assertEquals(100.0f, ops.roundUp(101.2323f, -1), 1f); }
