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_...
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...

ccall( (:foo, "libfoo"), Void, (Int32, Float64), x, y) 会按如下操作: ccall( (:foo, "libfoo"), Void, (Int32, Float64), convert(Int32, x), convert(Float64, y)) 如果标量值与&一起被传递作为Ptr{T}类型的参数时,值首先会被转换为T类型。 数组转换 把数组作为一个Ptr{T}参数传...

It converts all uppercase letters to lowercase letters, except within character-string constants. There are two usual solutions to the uppercase/lowercase problem:In the C subprogram, make the name of the C function all lowercase. Compile the f77 program with the -U option, which tells f77 ...

There are no null (zero-length) character-string variables. A one-byte character string assigned a null constant has the length zero.Example 2: No null character-string variables: CHARACTER S*1 S = ''During execution of the assignment statement, the variable S is precleared to blank, and ...
