 		 #142793 - const float...
Responding to: ???'s previous message
This makes a run time variable in your program which is a floating point value that has a read-only value. With the const specifier you have indicated to the compiler you do not want the value of this variable to be writable.

Some compilers will actually bury the constant variable into the code space in FLASH or ROM where it is intrinsically forced to be read only in normal operational mode.
