Node: Log Intrinsic, Next: Log10 Intrinsic, Previous: Loc Intrinsic, Up: Table of Intrinsic Functions
COMPLEX function, the exact type being that of argument X.
COMPLEX; scalar; INTENT(IN).
Intrinsic groups: (standard FORTRAN 77).
Returns the natural logarithm of X, which must
be greater than zero or, if type
COMPLEX, must not
See Exp Intrinsic, for the inverse of this function.
See Log10 Intrinsic, for the `common' (base-10) logarithm function.
