↳ | 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)
.
