• Are 'const' variables precomputed by default in C++?

  - by Gunnar

  Suppose I have variables for positions like const float latitude = 51.+11./60.+33.0461/3600.; const float longitude = 12.+50./60.+31.9369/3600.; and use them frequently in the program. Does the compiler precompute that? (This example should not produce much overhead, but you get the point.) Bonus point for pointing out location. ;) TIA
