NEAREST
— Nearest representable numberNEAREST(X, S)
returns the processor-representable number nearest to X
in the direction indicated by the sign of S
. RESULT = NEAREST(X, S)
X | Shall be of type REAL . |
S | Shall be of type REAL and not equal to zero. |
X
. If S
is positive, NEAREST
returns the processor-representable number greater than X
and nearest to it. If S
is negative, NEAREST
returns the processor-representable number smaller than X
and nearest to it. program test_nearest real :: x, y x = nearest(42.0, 1.0) y = nearest(42.0, -1.0) write (*,"(3(G20.15))") x, y, x - y end program test_nearest
