Here are some integer constants: 1 0 -100 32767 +15 Then we have real constants: 1.0 -0.25 2.0E6 3.333E-1 The E-notation means that you should multiply the constant by 10 raised to the power following the "E". Hence, 2.0E6 is two million, while 3.333E-1 is approximately one third.

Character Type Data objects of the character type include characters and strings (a string is a sequence of characters). The length of the string can be specified by len (see the examples below). WebFortran has five intrinsic data types: INTEGER, REAL, COMPLEX, LOGICAL and CHARACTER. Each of those types can be additionally characterized by a kind. Kind, basically, defines internal representation of the type: for the three numeric types, it defines the precision and range, and for the other two, the specifics of storage representation. …
