The comment associated with this states: * Later I will want the IEEE default of all exceptions masked. See the * 0.0 math manpage for why this is better. The 0.1 math manpage is empty. Whilst I'm uncertain of the references to 0.0 and 0.1, math(3M) does include some comments which imply that libm is designed to function correctly with all exceptions masked. Are there any plans to change the configuration word to 0x127f as implied in this comment?
