The DIGITS intrinsic function returns the number of significant digits in the model representing numbers of the same type and kind type parameter as the argument. The number returned is the number of significant radix digits (base 2 digits), not decimal digits. It accepts the following argument:

x: Must be of type integer or real. It can be scalar or array valued.

DIGITS is an inquiry function. The name of this intrinsic cannot be passed as an argument.
