Examples of bm.core.math.FixedPoint

bm.core.math.FixedPoint
Represents a decimal fixed point number, targeted to CLDC 1.0 platforms.
All operations on an instance of FixedPoint change the underlying value, so it's not Immutable. The reason is to prevent the creation of unneded objects which is not recommended for J2ME as causes performance problems.
Be aware that you can always expect more rounding problems with fixed point numbers than with floating point numbers.
This class allows the parsing and formatting of numbers using different decimal separator and grouping separator characters, so it is well suited for internationzalizable applications.
