 Calling Sequence x.__abs__() abs(x) x.__ceil__() ceil(x) x.__floor__() floor(x) x.__neg__() neg(x) x.__round__() round(x) x.__trunc__() trunc(x)

Parameters

 x - Expression object

Description

 • __abs__ function returns the absolute value of the Expression x.
 • This function can also be called by simply entering abs(x).
 • __ceil__ function returns the ceiling of the Expression x.
 • This function can also be called by simply entering ceil(x).
 • __floor__ function returns the floor of the Expression x.
 • This function can also be called by simply entering floor(x).
 • __neg__ function negates the Expression x.
 • This function can also be called by simply entering neg(x).
 • __round__ function rounds the Expression x.
 • This function can also be called by simply entering round(x).
 • __trunc__ function truncates the Expression x.
 • This function can also be called by simply entering trunc(x).

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
