MathCeil	Returns integer numeric value closest from above
MathCos	Returns the cosine of a number
MathExp	Returns exponent of a number
MathFloor	Returns integer numeric value closest from below
MathLog	Returns natural logarithm
MathLog10	Returns the logarithm of a number by base 10
MathMax	Returns the maximal value of the two numeric values
MathMin	Returns the minimal value of the two numeric values
MathMod	Returns the real remainder after the division of two numbers
MathPow	Raises the base to the specified power
MathRand	Returns a pseudorandom value within the range of 0 to 32767
MathRound	Rounds of a value to the nearest integer
MathSin	Returns the sine of a number
MathSqrt	Returns a square root
MathSrand	Sets the starting point for generating a series of pseudorandom integers
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.
