| 摘 要： | Neuron C是一种专门为Neuron芯片设计的程序设计语言。它在ANSIC的基础上进行了扩展，是开发LonWorks应用的有力工具。Neuron C不直接支持ANSIC中浮点数的算术和比较运算，但是它提供了一个浮点函数库，从而允许使用符合IEEE754标准的浮点数。文中详细介绍了Neuron C中浮点数据类型的定义、浮点常量的生成方法和浮点函数库的使用。通过一个实例LonWorks网络，演示了浮点数据的使用。

| Abstract: | Neuron C is a programming language that is designed for Neuron chips.It includes extensions to ANSI C,which make it a powerful tool for the development of LonWorks applications.Neuron C does not directly support the ANSI C arithmetic and comparison operation with floating-point values,however,there is a complete library of functions for floating-point math,which make it possible for using floating-point values according with IEEE 754 single precision format.The definition of floating-point data type,the methods of getting a floating-point constants and the library of functions for floating-point math were introduced in this paper in detail.Through a case LonWorks network,the using of floating-point data was illustrated. |
