单精度浮点型(float),在C++中,单精度浮点型(float)专指占用32位存储空间的单精度(single-precision)值。单精度在一些处理器上比双精度更快而且只占用双精度一半的空间,但是当值很大或很小的时候,它将变得不精确。当你需要小数部分并且对精度的要求不高时,单精度浮点型的变量是有用的。例如,当表示美元和分时,单精度浮点型是有用的。在foxpro中,单精度浮点型是为了提供兼容性,浮点数据类型在功能上等价于数值型。

  • 基于Realtek RTL9047AA 的车用 7端口网路交换器方案

    RTL9047A 为车用乙太网single chip 交换机方案,如下图port0~port3 总共提供4ports 100BASE-T1,不用外挂PHY可节省cost 及PCB空间;port4为 selection port可选择设定100BASE-T1或SGMII,其SGMII个外接CPU或对接相同型号switch做cascade扩充;port5为 selection port可选择设定传统100base-TX FE PHY, SGMII或 RGMII/MII/RMII,其100base-TX 界面作为车载Diagnostic界面;port6为RGMII/MII/RMII 界面,可用来外接CPU或扩充网路界面等应用。

  • 路斯特ServoOne手册

    German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.So in future, if you should need more than today ' smarket can offer you, now everything isgoing to be alright. With our new high-performance ServoOne drive series you will experi-ence

  • SiI9135芯片手册

    Introduction The Sil9135/Sil9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs is a second-generation dual-input High Definition Multimedia Interface(HDMI)receiver. It is software-compatible with the Sil9133receiver, but adds audio support for DTS-HD and Dolby TrueHD. Digital televisions that can display 10-or 12-bit color depth can now provide the highest quality protected digital audio and video over a single cable. The Sil9135and Sil9135A devices, which are functionally identical, can receive Deep Color video up to 12-bit,1080p @60Hz. Backward compatibility with the DVI 1.0specification allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set-top boxes and PCs. Silicon Image HDMI receivers use the latest generation Transition Minimized Differential Signaling(TMDS) core technology that runs at 25-225 MHz.The chip comes pre-programmed with High-bandwidth?
