The simplify endpoint reduces a fraction to lowest terms and returns its decimal value, mixed-number form and whether it is whole. The calc endpoint adds, subtracts, multiplies or divides two fractions (or whole numbers, mixed numbers or decimals) and returns the simplified result. The fromdecimal endpoint turns a decimal into a fraction — exactly for terminating decimals, and precisely for repeating decimals written with parentheses (0.1(6) → 1/6). Inputs may be n/d, an integer, a mixed number like '1 1/2', or a decimal. Pure local, no key."
