A simple and generic question that I can not find a straight answer for. The rule that I am debating is based on that I should write 2 if it is a measured value. In this situation the 2 is a rounded measured value from 1.96 which would make me think to use two now instead of 2. What is technically correct and is the technical answer best for a user experience?
When to use TWO and When to use 2?
