+
+    Store sine & cosine tables as doubles instead of floats
+    
+    Since they're used as doubles in the calculations, might as well store them
+    that way instead of converting when read from the table at runtime.
+    
+    Costs about 4k more storage in the binary for the doubled tables.
+    
+    Also gets rid of 900 clang warnings, of the form:
+    
+    Clock.c:1708:11: warning: implicit conversion loses floating-point precision:
+          'double' to 'float' [-Wconversion]
+    0.000000, 0.001745, 0.003490, 0.005235, 0.006981, 0.008726, 0.010471, 0.012217,
+    
+    (one for each table entry)
