Overview

Raised when a mathematical function is evaluated outside of its domain of definition.

For example, since cos returns values in the range -1..1, its inverse function acos is only defined on that interval:

Math.acos(42)

produces:

Math::DomainError: Numerical argument is out of domain - "acos"

.exception	With no argument, or if the argument is the same as the receiver, return the receiver.
.new	Construct a new ::Exception object, optionally passing in a message.

#==	Equality—If obj is not an ::Exception, returns `false`.
#backtrace	Returns any backtrace associated with the exception.
#backtrace_locations	Returns any backtrace associated with the exception.
#cause	Returns the previous exception ($!) at the time this exception was raised.
#exception	With no argument, or if the argument is the same as the receiver, return the receiver.
#inspect	Return this exception's class name and message.
#message	Returns the result of invoking `exception.to_s`.
#set_backtrace	Sets the backtrace information associated with `exc`.
#to_s	Returns exception's message (or the name of the exception if no message is set).
