259. If an error was encountered when processing a floating-point conversion directive with assignment suppressed, the scanf() family of functions might not return the correct value.
260. When using the g or G conversion specifiers in the fprintf() family of functions, the number zero could sometimes be printed in an exponential format like "0e+00". It should be printed in a non-exponential format like "0".
261. Several <math.h> functions could set errno inappropriately, based on a previous floating-point math operation rather than the current operation.
262. If a domain or range error had occurred in any previous floating-point operation, sinh() and cosh() calls might return the wrong values.
(William K. Watts, Jr.)
263. The sqrt() function would set errno to ERANGE if its argument was negative. This is a domain error, so it should set errno to EDOM in this case.
(William K. Watts, Jr.)
264. The fmod() function could return the wrong value when the second argument was negative.

1. In some situations, fread() reread the first 1K or so of the file.
