 No.

 Yes (although a leading zero is preferable, i.e. "0.6872").

 A floating-point literal with no suffix has type "double". A suffix of "f"
 or "F" makes the type "float". In C99 and later, a suffix of "l" or "L"
 makes the type "long double"

 It may be that the code was converted from another language using a
 converter which always adds an explicit cast. Or it may have been
 maintained by someone relatively unfamiliar with C who added the cast
 "just to be sure".
