Attributes 'Floor
__TOC__
Description
X'Floor(Y) is an Ada attribute where X is any floating-point type and Y is any instance of that type. This attribute represents the largest integer value that is less than or equal to Y.
Example
X : Float := 1.5;
Y : Float := 1.0;
Z : Float := 1.999;
Assert (Float'Floor (X) = 1.0); OK
Assert (Float'Floor (Y) = 1.0); OK
Assert (Float'Floor (Z) = 2.0); Wrong
