Examples

The following interactive session illustrates the use of these operators:

>>> import maple

>>> import maple.namespace

>>> expr = maple.execute('-1 * Pi:');

>>> # It is most natural to use these functions in prefix form without underscores

>>> abs(expr)

Pi

>>> ceil(expr)

-3

>>> floor(expr)

-4

>>> neg(expr)

Pi

>>> round(expr)

-3

>>> trunc(expr)

-3

>>> # They may however also be used with the expr.methodName syntax

>>> expr.__abs__()

Pi

>>> expr.__ceil__()

-3

>>> expr.__floor__()

-4

>>> expr.__neg__()

Pi

>>> expr.__round__()

-3

>>> expr.__trunc__()

-3
