Denormalized floating point in Objective-C?

http://stackoverflow.com/questions/9350810/denormalized-floating-point-in-objective-c

floats appear again. Interestingly FLT_MIN and DBL_MIN respectively are defined to the smallest non denormalized number.. on iOS Mac OS X and Linux . Strange things happen using DBL_MIN 2.0 in your code the compiler happily sets a denormalized constant.. as the arm CPU touches it it is set to zero double test DBL_MIN 2.0 printf test 0.0 d n test 0.0 printf DBL_MIN 2 0.0 d n DBL_MIN..
