type :: return_value ! function body end function 例如,下面是一个简单的Fortran函数,它计算两个整数的和: function add_numbers (a, b) result(sum) integer :: a, b, sum sum = a + b end function 在这个函数中,参数a和b是整数类型,而返回值sum也是整数类型。函数体只包含一行代码,它将参数a和...

Results can even change sign due to the sin curve being too close to an x-intercept value when evaluated. To maintain consistency in this case, you can assure that the compiler generates code that calls a function. According to the x86 ABI, a function call must push its arguments on the...
