Introduction
When playing the "Number Between" game, Caitlin reveals how she perceives the decimal part of a number as another whole number. Often she ignores the decimal point completely. She finds it easy to think of numbers between 0.0 and 1.0, between 0.0 and 0.5 and between 0.3 and 0.5 because these can be done by ignoring the decimal point. However, she cannot agree that there is a number between 0.4 and 0.5, even when the interviewer suggests one and the computer game then accepts it.
