Convert integer to string write(int_str, '(I20)') int_num print *, 'Integer as string: ', trim(int_str) ! Convert real number to string write(real_str, '(F20.2)') real_num print *, 'Real number as string: ', trim(real_str) end program number_to_string 在这个示例中,write ...
方法1:使用内置函数CONVERT和CHAR 使用内置函数CONVERT和CHAR可以有效地将浮点数转换为字符串。以下是使用这种方法的示例代码: fortran program float_to_string implicit none real :: number = 3.14159 character(len=20) :: str_number str_number = char(convert(number), len=str_number) write(*,*) str_...
integer:: totalreal:: averagecomplex:: cxlogical:: donecharacter(len =80) :: message! a string of 80 characters 稍后您可以为这些变量赋值,例如, total=20000average=1666.67done= .true.message= “A big Hello from IOWIKI”cx= (3.0,5.0) ! cx =3.0+5.0i 您还可以使用内部函数cmplx,将值赋给复...
8.3.2 传递结构体 (参考代码:"passtype_degree") 传递结构体时需注意,即使两个结构体完全一样,但其分别独立定义,编译器也认为不是同一类。 因此虚参实参如果传递结构体,必须是由同一个定义Type得到的结构体实例. 一般采用模块定义Type,在调用者和子程序中分别调用同一个模块来定义实参和虚参。(参考代码:"pass...

Your sample code is great, but it's a little too specialized to the example program I posted. The real world code that I have converts a string input to an associated double array as output. The string passed in and the name of the double array returned are not related in any ...
