在Python.NET中指定要存储的有效数字

可能的使用场景

默认情况下，Aspose.Cells在Excel文件中存储双精度值时保留17位有效数字，不同于Microsoft Excel仅存储15位有效数字。你可以通过CellsHelper.significant_digits属性将此行为从17位改为15位有效数字。

指定要在Excel文件中存储的有效数字

以下示例代码强制Aspose.Cells在存储双精度值时使用15位有效数字。请查看输出Excel文件（将扩展名改为.zip以检查存储的值）。下图显示了此设置如何影响存储的值：

示例代码

from aspose.cells import Workbook, CellsHelper
import aspose.cells
import os
import pytest

# Set significant digits to 15
CellsHelper.set_significant_digits(15)

# Create new workbook
workbook = Workbook()

# Access first worksheet
worksheet = workbook.worksheets[0]

# Set value with extended precision
cell = worksheet.cells.get("A1")
cell.put_value(1234567890123456.001234567890123456)

# Save modified workbook
workbook.save("output.xlsx")

import os
from aspose.cells import Workbook, CellsHelper

# The path to the documents directory.
current_dir = os.path.dirname(os.path.abspath(__file__))
data_dir = os.path.join(current_dir, "data")

# Set significant digits to 15 like MS-Excel
CellsHelper.set_significant_digits(15)

# Create workbook
workbook = Workbook()

# Access first worksheet
worksheet = workbook.worksheets[0]

# Access cell A1
c = worksheet.cells.get("A1")

# Put double value with 15 significant digits
c.put_value(1234567890.123451711)

# Save the workbook
output_dir = os.path.join(current_dir, "output")
if not os.path.exists(output_dir):
    os.makedirs(output_dir)

workbook.save(os.path.join(output_dir, "out_SignificantDigits.xlsx"))
