| Summary | 0000604: Add text for subnormal argument case | ||||
| Description | The Return Values section of tgamma() does not mention what should happen for subnormal arguments. Other functions, such as asin(), asinh(), atan(), atanh(), expm1(), hypot(), log1p(), sin(), sinh(), tan(), tanh(), do mention subnormal arguments; but all of those are underflow, while this is overflow or very large. | ||||
| Desired Action | Add MX shaded text: If x is subnormal and 1/x is representable, 1/x should be returned. | ||||

At page 2105 line 66587, replace: These functions shall compute the gamma( ) function of x. with a copy of page 1214 line 40039, dropping the log<sub e> and the bars around the <capital-gamma>(x), so that it looks like: These functions shall compute <capital-gamma>(x) where <capital-gamma>(x) is defined as <math-stuff> dt. At page 2105 line 66593 change: shall return Gamma(x). to: shall return the gamma of x. At page 2105 before line 66604 insert a new paragraph, shaded MXX: If x is subnormal and 1/x is representable, 1/x should be returned. |
