### Question:
ParseBigDecimal implements IsParser<BigDecimal> { @Override public void setCell(BigDecimal o, Cell cell, Field field) { if (o != null) { cell.setCellValue(o.doubleValue()); } }  @Override BigDecimal parse(Object o, Field field); @Override void setCell(BigDecimal o, Cell cell, Field field);  }### Answer:
@Test public void setCell() throws Exception { Cell cell = CellGenerateUtil.create(); parseBigDecimal.setCell(null, cell, null); assertEquals("", cell.getStringCellValue()); parseBigDecimal.setCell(expected, cell, null); assertEquals(cell.getNumericCellValue(), expected.doubleValue(), 0.01d); }
