Properties

divisionByZero bool divisionByZero [@property getter]: IEEE _decimal context errors. By default, no error is set.
enabledExceptions ExceptionFlags enabledExceptions [@property getter]: Extracts current enabled exceptions.
inexact bool inexact [@property getter]: IEEE _decimal context errors. By default, no error is set.
invalidOperation bool invalidOperation [@property getter]
overflow bool overflow [@property getter]
underflow bool underflow [@property getter]: IEEE _decimal context errors. By default, no error is set.

Static functions

disableExceptions void disableExceptions(ExceptionFlags group)
void disableExceptions(): Disables specified exceptions. Multiple exceptions may be ORed together.
enableExceptions void enableExceptions(ExceptionFlags group): Enables specified exceptions. Multiple exceptions may be ORed together.
hasFlags bool hasFlags(ExceptionFlags group): Checks if the specified error flags are set. Multiple exceptions may be ORed together.
raiseFlags void raiseFlags(ExceptionFlags group): Sets specified error flags. Multiple errors may be ORed together.
resetFlags void resetFlags(ExceptionFlags group)
void resetFlags(): Unsets specified error flags. Multiple errors may be ORed together.
restoreFlags void restoreFlags(ExceptionFlags group): Enables specified error flags (group) without throwing corresponding exceptions.
saveFlags ExceptionFlags saveFlags(): Returns the current set flags.

Static variables

precision Precision precision;: Gets or sets the precision applied to peration results. See Precision for details.
rounding RoundingMode rounding;: Gets or sets the rounding mode used when the result of an operation exceeds the _decimal precision. See RoundingMode for details.
