导入HTML时避免大数字的指数表示法

有时候你的HTML包含像1234567890123456这样长于15位的数字，当你将HTML导入Excel时，这些数字会变成指数表示法如1.23457E+15。如果你希望数字按原样导入而不转换为指数形式，请在加载HTML时使用HTMLLoadOptions.GetKeepPrecision()属性并将其设置为true。
以下示例代码说明了HTMLLoadOptions.GetKeepPrecision()属性的用法。API将按原样导入数字，而不将其转换为指数表示法。
#include <iostream>
#include <vector>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;
int main()
{
Startup();
U16String html = u"<html><body><p>1234567890123456</p></body></html>";
std::vector<uint8_t> byteArray;
for (int32_t i = 0; i < html.GetLength(); ++i)
{
char16_t c = html[i];
if (c <= 0x7F)
byteArray.push_back(static_cast<uint8_t>(c));
}
HtmlLoadOptions loadOptions = HtmlLoadOptions(LoadFormat::Html);
loadOptions.SetKeepPrecision(true);
Vector<uint8_t> data(byteArray.data(), static_cast<int32_t>(byteArray.size()));
Workbook workbook(data, loadOptions);
Worksheet sheet = workbook.GetWorksheets().Get(0);
sheet.AutoFitColumns();
U16String outDir(u"..\\Data\\02_OutputDirectory\\");
workbook.Save(outDir + u"outputAvoidExponentialNotationWhileImportingFromHtml.xlsx", SaveFormat::Xlsx);
std::cout << "File saved successfully." << std::endl;
Cleanup();
return 0;
}
