# Known Bugs and Limitations¶

## Mathematical Classes¶

### MRational¶

When using the method setDouble(double), the nominator and denominator will be determined with an accuracy of 6 digits. This results in the following side-effects:
• floating point numbers may result in rational numbers with large nominators/denominators
• for values bigger than 9.999.999 the denominator will be set to 0 and the resulting rational number will become 1/0

### MOpMatrix¶

The usage of MOpNumber@s in @OpMatrix is discouraged. Especially the method determinant() may result in an infinite loop. Use NumberMatrix with @MOpNumber@s instead.
