Subject: REM(inf,y), REM(x,0.0)
NUMBER: F03/0036
TITLE: IEEE_REM()
KEYWORDS: IEEE-754, remainder()
DEFECT TYPE: ???
STATUS: For consideration
QUESTION:
What is REM(infinity,Y)? REM(X,0.0)?
What is REM(X,Y) if X and/or Y is NaN?
DISCUSSION:
IEEE-754 requires (in 7.1) both REM(infinity,Y) and REM(X,0.0)
shall be a NaN and raise invalid.
REM(X,Y) when both X and Y are NaN shall be a NaN, and should be
one of NaN arguments.
REM(X,Y) when one of X and Y is a NaN shall be a NaN, and should
the NaN argument.
