DIGITS 90Returns the number of significant digits in the model representing the argument.SynopsisDIGITS(X)ArgumentThe argument X is of type integer or real.Return ValueAn integer value representing the number of digits in the model representing the specified kind.DIM 77This intrinsic returns the difference X-Y if the value is positive, otherwise it returns 0.SynopsisDIM(X, Y)ArgumentsX must be of type integer or real. Y must be of the same type and kind as X.Return ValueThe result is the same type and kind as X with the value X-Y if X>Y, otherwise zero.DOT_PRODUCT 90Perform a dot product on two vectors (arrays).SynopsisDOT_PRODUCT(VECTOR_A, VECTOR_B)ArgumentsVECTOR_A must be an array of rank one of type numeric (integer, real, complex) or logical.VECTOR_B must be numeric if VECTOR_A is numeric, or logical if VECTOR_A is logical. It musthave the same rank and size as ARRAY_A.Fortran Intrinsics 207
