NAME

SCALE - Returns (x)(b**i), where b is the base in the real number model representation of x

SYNOPSIS

SCALE ([X=]x, [I=]i)

STANDARDS

Fortran

DESCRIPTION

The SCALE intrinsic function returns (x)(bi), where b is the base in the real number model representation of x. For more information on the real number model, see the models(3i) man page. It accepts the following arguments:

x: Must be of type real
i: Must be of type integer

SCALE is an elemental function. The name of this intrinsic cannot be passed as an argument.

RETURN VALUES

The result type and type parameter are the same as x. The result has the value (x)(bi), where b is defined in the model for real numbers representing values of x, provided that this result is within range. Argument i should be within the range of MINEXPONENT(x) <= i <= MAXEXPONENT(x). If i is outside this range, the results are unpredictable.

EXAMPLES

SCALE(3.0,2) yields 12.0 for reals.
