I already know the names of all my constants and what they mean. I wanted a file that I could open and peek at numerical values. No gcc, no web browser. Just some float.h that I can open with vim, less, or grep to quickly get a value in 2 seconds.
Such a float.h used to exist on my hard drive. I guess that changed with some gcc update. Telling me to read the IEEE 754 standard is like telling me that I need to know the DNA sequence for a Fuji apple when all I really want is to eat one.
