ASCII码表 ASCII码表字符解释 2.3.2 数值类型 Python提供的3种数值类型: 整数类型:与数学中的整数一致,包含正、负、0。一个整数有二进制、八进制、十进制、十六进制4种表示方式。 浮点数类型:与数学中的小数一致,没有取值范围限制,可正、可负。有两种表示形式,一种是小数点的形式,另外一种是科学计数法。浮点数...
In the same way that you can return a value from a function in Python, the operating system expects an integer return value from a process once it exits. This is why the canonical C main() function usually returns an integer: C minimal_program.c int main(){ return 0; } This examp...

在源代码的第一行和第二行中,您可以设置一个特殊的标记来声明文件的编码。如果不需要ASCII字符,我们建议您使用UTF-8作为编码。 出于调试目的,您可以使用print来简化输出。使用%运算符,您可以实现类似于C函数的功能printf()。输出显示在CODESYS的消息视图中。
