Common use of Calculation by computer Clause in Contracts

Calculation by computer. The calculation of the usable field strength with the simplified multiplication method is based on the probability integral for a normal distribution: 2π L( x) = 1 × ∫ −∞ − t 2 dt This integration can, however, be avoided in the practical calculation by replacing it with a polynomial approximation as follows: with a1 = 0.196854 a2 = 0.115194 a3 = 0.000344 a4 = 0.019527 L(x) = 1 – ½(1 + a1x + a2x2 + a3x3 + a4x4)–4 + ε(x) ε(x) represents the error between the approximation and the exact value, obtained by the probability integral. Since |ε(x)| is less than 2.5 . 10–4, this error can be neglected. The above approximation was used to calculate the multiple interference by the simplified multiplication method.
