Because 1.2E6 can be represented exactly by single precision.

You can use -CF64 to force floating point constants to have at least 64 
bits precision. Or you can use {$excessprecision on} to force the 
compiler to evaluate all floating point expressions always using the 
maximum precision supported by the FPU.
