Wikipedia
irrational
Irrationality is cognition, thinking, talking, or acting without inclusion of rationality. It is more specifically described as an action or opinion given through inadequate use of reason, or through emotional distress or cognitive deficiency. The term is used, usually pejoratively, to describe thinking and actions that are, or appear to be, less useful, or more illogical than other more rational alternatives.Irrational behaviors of individuals include taking offense or becoming angry about a situation that has not yet occurred, expressing emotions exaggeratedly (such as crying hysterically), maintaining unrealistic expectations, engaging in irresponsible conduct such as problem intoxication, disorganization, and falling victim to confidence tricks. People with a mental illness like schizophrenia may exhibit irrational paranoia. These more contemporary normative conceptions of what constitutes a manifestation of irrationality are difficult to demonstrate empirically because it is not clear by whose standards we are to judge the behavior rational or irrational.

irrational
In mathematics, irrational refers to a type of number that cannot be expressed as a simple fraction or ratio of two integers. It is a number that cannot be written as a/b, where a and b are integers and b ≠ 0. The decimal representation of an irrational number is non-terminating and non-repeating. Common examples of irrational numbers include the square root of 2, Pi, and the golden ratio. In a more broader or general sense outside mathematics, irrational can refer to something that is not logical or not based on reason; describing behavior or actions that lack sound judgement, clear thinking or reasoning.
