MathTan	Returns the tangent of a number
MathIsValidNumber	Checks the correctness of a real number

What's new in MQL5

Added hyperbolic trigonometric functions and the MathSwap function for changing the byte order in ushort, uint and ulong integer types. The need for such a transformation often arises when working with the Network functions.

The Mathematics section contains the ready-made libraries for working with random distributions, fuzzy logic and neural networks. It also contains functions for solving differential equations, clustering, statistical analysis and optimization tasks.
