WebIt stores the floating point numbers, such as 2.0, 3.1415, -100.876, etc. Traditionally there are two different real types, the default real type and double precision type. However, Fortran 90/95 provides more control over the precision of real and integer data types through the kind specifier, which we will study in the chapter on Numbers. WebThe COMMON block, a piece of shared memory in the computer, is another method for passing information between program units. Data stored in a COMMON block is not passed between program units via argument lists, but through the COMMON statement near the beginning of each program unit.
