Discussion

This value compares less than or equal to all positive normal numbers. There may be smaller positive numbers, but they are subnormal, meaning that they are represented with less precision than normal numbers.

This value corresponds to type-specific C macros such as FLT_MIN and DBL_MIN. The naming of those macros is slightly misleading, because subnormals, zeros, and negative numbers are smaller than this value.
