Proposal:

Hide

1) Move the statement of the allowed values of 0^0 from the definition of the ^ operator in 5.4.6 to the semantics statement in the definition of POWER() in 5.16.46.

2) We should add the following semantic constraints to POWER():

a) POWER(0,0) is implementation-defined, but shall be one of 0,1, or an Error
b) POWER(0,b), where b < 0, shall return an error.
c) POWER(a,b), where a<=0 and INT(b)!=b, is implementation defined.

Resolution:

Hide

Removed 0^0 statement from operator ^.

Added to Semantics of POWER:

POWER(0,0) is implementation-defined, but shall be one of 0,1, or an Error.
POWER(0,b), where b < 0, shall return an error.
POWER(a,b), where a<=0 and INT(b)!=b, is implementation-defined.

Show
Removed 0^0 statement from operator ^. Added to Semantics of POWER: POWER(0,0) is implementation-defined, but shall be one of 0,1, or an Error. POWER(0,b), where b < 0, shall return an error. POWER(a,b), where a<=0 and INT(b)!=b, is implementation-defined.
