### The settings of the program - extreme number options: Mathematics

On the "Math" tab, there are 6 options for configuring the calculation: setting the type of root calculation, speeding up the calculation, etc.

1. Option "Use alternative ways to extract the root" - when this option is enabled, you can specify 2 ways to find the root - "algorithm for extracting the root by column" - the algorithm for finding the root is used Shifting root algorithm, ""Fast convergent method of finding the root" - when selected, the number of iterations option is available-sets the number that affects the accuracy of the calculated function, the more, the more accurate the calculation will be, but the longer the calculation will take
2. Setting "Calculate the value of trigonometric functions by the Taylor formula" - when enabled (it is only available in a registered copy of the program, not lower than the Professional license) - more precise calculation of trigonometric functions (sine, cosine, tangent, cotangent, secant, cosecant) by the Taylor method is available - in this case, you can get a more precise value of the calculated function, the parameter " Precise (number of iterations) sets the number that affects the accuracy of the calculated function, the larger it is, the more accurate the calculation will be, but the longer the calculation will take
3. Overflow setting "integer Overflow" - the option configures the setting of the operation task in case of overflow (if a number is reached during the operation being performed, the value of which is greater than the maximum value of a computer-type number, a variable type (usually int) in a given program number type
4. Overflow setting "double-precision Overflow" - the option configures the setting of the operation task in case of overflow (if a number is reached during the operation being performed, the value of which is greater than the maximum value of a computer-type number, a variable type (usually double) in a given program number type
5. Setting the calculation optimization to "Use flow-preserving calculation optimization" - while accelerating the degree and root calculations much faster, the calculation is several times faster than the usual calculation (extreme number). Options for degree and root are available.
