Basic Examples  (2)

Limit a calculation to use at most 100 digits of precision:

Do a computation with fixed 24 digit precision:

Applications  (1)

Iterate a map using fixed precision:

If the precision is not fixed, it eventually drops to zero in the 100 iterations:

Possible Issues  (1)

When $MaxPrecision is set, some computations may not get correct results:

The actual value is much smaller:
