Synonym: Analytic expression = Explicit expression

Mathematical expression expressed using a finite number of basic arithmetic operations over the numbers, elementary functions or tabulated special functions and may include infinite series and continued fractions.

The key difference with closed-form expression is that analytic expression may include tabulated special functions, infinite series and continued fractions.

The key benefit of dealing with closed-form expressions is that they are:

• well tabulated with precision enough for the majority of engineering applications
• implemented as fast-computable algorithms with computer precisions (usually 64 bit and 128 bit) on modern  computers
• available as fast-computing algorithms with arbitrary user-defined precision
