Products Affected
Mac OS 8.1
MathLib is a library of transcendental functions, which includes sine and cosine. Mac OS 8.1 includes MathLib v3. On some computers this newer version does not load--the previous version loads instead.
MathLib v3 provides a higher degree of accuracy than the previous MathLib library, which may cause slightly different calculation results. For example, the value of pi in MathLib v2 is calculated to 54 decimal places. The value of pi in MathLib v3 is calculated to 107 decimal places.
On the following computer models, MathLib v2 is loaded from ROM (instead of the newer v3 version provided with Mac OS 8.1). All other supported computer models with Mac OS 8.1 will load MathLib v3.
