Compares two Float objects numerically.
[Android.Runtime.Register("compareTo", "(Ljava/lang/Float;)I", "")]
public int CompareTo (Java.Lang.Float anotherFloat);[<Android.Runtime.Register("compareTo", "(Ljava/lang/Float;)I", "")>]
member this.CompareTo : Java.Lang.Float -> intParameters
- anotherFloat
- Float
the Float to be compared.
Returns
the value 0 if anotherFloat is
numerically equal to this Float; a value
less than 0 if this Float
is numerically less than anotherFloat;
and a value greater than 0 if this
Float is numerically greater than
anotherFloat.

Remarks
Compares two Float objects numerically.
This method imposes a total order on Float objects with two differences compared to the incomplete order defined by the Java language numerical comparison operators (<, <=, ==, >=, >) on float values.
<ul><li> A NaN is <em>unordered</em> with respect to other values and unequal to itself under the comparison operators. This method chooses to define Float.NaN to be equal to itself and greater than all other double values (including Float.POSITIVE_INFINITY).
<li> Positive zero and negative zero compare equal numerically, but are distinct and distinguishable values. This method chooses to define positive zero (+0.0f), to be greater than negative zero (-0.0f). </ul>
This ensures that the natural ordering of Float objects imposed by this method is consistent with equals; see this discussion for details of floating-point comparison and ordering.
