EXPONENT ( X )
X : Real, any kind;
Result: Integer, default kind. |

Returns the exponent of X in the real model for that kind of floating-point number.
If the value of X is representable in that model, the result satisfies the relationship X = FRACTION(X)*(REAL(RADIX(X),KIND(X))**EXPONENT(X),
or if X is an IEEE infinity or NaN, the result is equal to HUGE(0).
Note that if X is double-double precision, the result of EXPONENT(X) is accurate but FRACTION(X) might not be.
Like many intrinsic functions, this is elemental; the result has the same shape as X, with the operation being applied elementwise.
