Maple allows you to perform precision computations with quantities involving tolerances. Tolerances are entered and displayed using standard notation, for example, 1.45 ± 0.05.
- Tolerances are recognized by all standard arithmetic operators, for example,

 - Tolerances support many built-in functions, including square roots, exponentials, trigonometric and special functions.
 - Easily enter the ± sign using palettes or your keyboard.
 - Combine tolerances with units in the same computation.
 - Tolerances maintain the same level of precision as standard numeric values.
 - Extract nominal and tolerance values from a term for further computations.
