PC机:
代码使用的Qt C++
代码:
QPointF point(1028459388*0.0000001,xxx);
qDebug("pointx=%3.7f pointy=%3.7f",point.rx(),point.ry());
结果;
pointx=102.8459388 pointy=xxx
ARM板子:
使用的Qt,交叉编译
代码:
QPointF point(1028459388*0.0000001,xxx);
qDebug("pointx=%3.7f pointy=%3.7f",point.rx(),point.ry());
结果:
pointx=102.8459396 pointy=xxx
