FloatMath

extends Object
java.lang.Object
   ↳ android.util.FloatMath

This class was deprecated in API level 22.
Use Math instead.

Class Overview

Math routines similar to those found in Math.

Historically these methods were faster than the equivalent double-based Math methods. On versions of Android with a JIT they became slower and have since been re-implemented to wrap calls to Math. Math should be used in preference.

Summary

Public Methods

public static float ceil (float value)

Added in API level 1

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)

Added in API level 1

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 exp (float value)

Added in API level 17

Returns the closest float approximation of the raising "e" to the power of the argument.

Parameters
value to compute the exponential of
Returns
  • the exponential of value

public static float floor (float value)

Added in API level 1

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
