ekatz added a parent revision: D69770: Add recoverable string parsing errors to APFloat.

Previously the supported special strings were:
inf, INFINITY, +Inf,
-inf, -INFINITY, -Inf,
nan, NaN,
-nan, -NaN,

Now it is extended to the following (which may be prefixed with a '-' or a '+' sign):
INF, INFINITY, inf, Inf, infinity, Infinity,
nan, NaN, NAN

The NaNs may be prefixed with 'q' or 'Q' for explicitly defining a Quiet NaN (implicit if no prefix exists), or 's' or 'S' for defining a Signaling NaN.
A payload for a NaN can be specified as a suffix. It may be a octal/decimal/hexadecimal number in parentheses or without.
