Inquiry Intrinsic Function (Generic): Returns the smallest number in the model representing the same type and kind parameters as the argument.
result = TINY (x)
x |
(Input) Must be of type real; it can be scalar or array valued. |
The result is a scalar with the same type and kind parameters as x. The result has the value b emin - 1. Parameters b and emin are defined in Model for Real Data.
If X is of type REAL(4), TINY (X) has the value 2 -126.
The following shows another example:
REAL(8) r, result
r = 487923.3D0
result = TINY(r) ! returns 2.225073858507201E-308
