Intrinsic procedure specifications
Chapter 11 551
Argument
X must be of type real.
Result type
Default integer.
Result value
The result has a value equal to the exponent
e
of the model representation (see “The Real
Number System Model” on page 509) for the value of X, provided X is nonzero and
e
is within
the range for default integers. The result is undefined if the processor cannot represent
e
in
the default integer type. EXPONENT(X) has the value zero if X is zero.
FLOOR(A)
Description
Returns the greatest integer less than or equal to its argument.
Class
Elemental function.
Argument
A must be of type real.
Result type/
type parameters
Default integer.
Result value
The result has a value equal to the greatest integer less than or equal to A. The result is
undefined if the processor cannot represent this value in the default integer type.
FLUSH(LUNIT)
Description
Flush pending I/O on a logical unit.
