Standard language features

When solving various problems using a computer, it is necessary to calculate the logarithm or modulus of a number, the sine of an angle, etc.

Table of standard functions of school algorithmic language

Name and mathematical designation of the function		Function pointer
Absolute value (modulus)	| x |	abs (x)
Square root		sqrt (x)
Natural logarithm	ln x	ln (x)
Decimal logarithm	lg x	lg (x)
Exponent (degree of number e ~ 2.72)	e x	exp (x)
The sign of the number x (- 1 if x <0; 0, if x = 0; 1, if x> 0)	sign x	sign (x)
Integer part of x (i.e. maximum integer not exceeding x)		int (x)
Minimum of numbers x and y		min (x, y)
Maximum of numbers x and y		max (x, y)
The quotient of dividing x by integer y		div (x, y)
The remainder of dividing integer x by integer y		mod (x, y)
Random number from 0 to x - 1		rnd (x)
Sine (angle in radians)	sin x	sin (x)
Cosine (angle in radians)	cos x	cos (x)
Tangent (angle in radians)	tg x	tg (x)
Cotangent (angle in radians)	ctg x	ctg (x)
Arcsine (main value in radians)	arcsin x	arcsin (x)
Arccosine (principal in radians)	arccos x	arccos (x)
Arctangent (most important in radians)	arctg x	arctg (x)
Arccoat tangents (most important in radians)	arcctg x	arcctg (x)

As arguments of functions, you can use constants, variables and expressions. For example:

Each programming language has its own set of standard functions.
