android.util.FloatMath

java.lang.Object
android.util.FloatMath

Math routines similar to those found in Math. Performs computations on float values directly without incurring the overhead of conversions to and from double.

On one platform, FloatMath.sqrt(100) executes in one third of the time required by java.lang.Math.sqrt(100).

Details

Public Methods

public static float ceil(float value)

Returns the float conversion of the most negative (i.e. closest to negative infinity) integer value which is greater than the argument.

Parameters

value to be converted

Returns

  • the ceiling of value

public static float cos(float angle)

Returns the closest float approximation of the cosine of the argument.

Parameters

angle to compute the cosine of, in radians

Returns

  • the cosine of angle

public static float floor(float value)

Returns the float conversion of the most positive (i.e. closest to positive infinity) integer value which is less than the argument.

Parameters

value to be converted

Returns

  • the floor of value

public static float sin(float angle)

Returns the closest float approximation of the sine of the argument.

Parameters

angle to compute the cosine of, in radians

Returns

  • the sine of angle

public static float sqrt(float value)

Returns the closest float approximation of the square root of the argument.

Parameters

value to compute sqrt of

Returns

  • the square root of value
