2020年1月7日 · Literal constants need special care. 1.0/3.0 and 1._wp/3._wp have significantly different values for instance. Some functions will also return default real value (i.e. single precision) unless requested, such as the real intrinsic.

2020年1月6日 · Some函数的 1.0/3.0 和 1._wp/3._wp 值也将返回默认值 (即单精度)，例如 real 函数。 页面原文内容由 Stack Overflow 提供。 腾讯云小微IT领域专用引擎提供翻译支持.

PI = 3.141592653589793_WP while since the intrinsic functions are generic, they will automatically use the correct data type and kind, which means that the argument determines which kind the result should have (usually the same as the argument).

Fortran语言使用的特殊字母表被称为Fortran字符集。 目前Fortran字符集由97个字符组成： Fortran对字母大小写不敏感。 A和a是两个相同的字母。 语句分类：可执行部分+不可执行部分。 &符号：进行标记并在下一行继续这一行书写，直到结束。 !符号：注释说明符号。 语句标号：第四行，以数字开始，语句标号可以是1~99999中任何一个数字，是Fortran语句中的“名字”，使用它可以在程序的其他地方引用这条语句。 标号数字在程序单元中必须是唯一的。 output = …

2017年10月17日 · This generic accepts any real or complex argument and returns a result of the same type and kind as the argument. In this case, the argument 3.0 is a real (literal constant) of default kind, so the result is also a real of default kind. On the other hand, the expression (3.0_wp)**(1.0/2.0) is a real with kind parameter wp.
