MathAbs()
double MathAbs(double value)
Returns the absolute value (modulus) of the specified numeric value.
Parameters:
value - Numeric value.
Sample:
double dx=-3.141593, dy;
// calc MathAbs
dy=MathAbs(dx);
Print("The absolute value of ",dx," is ",dy);
// Output: The absolute value of -3.141593 is 3.141593
MathArccos()
double MathArccos(double x)
The MathArccos function returns the arccosine of x within the range 0 to π (in radians). If x is less than -1 or exceeds 1, the MathArccos returns NaN (indeterminate value).
Parameters:
x - Value between -1 and 1 the arccosine of which to be calculated.
Sample:
double x=0.32696, y;
y=asin(x);
Print("Arcsine of ",x," = ",y);
y=acos(x);
Print("Arccosine of ",x," = ",y);
//Output: Arcsine of 0.326960=0.333085
//Output: Arccosine of 0.326960=1.237711
MathArcsin()
double MathArcsin(double x)
The MathArcsin function returns the arcsine of x in the range -π/2 to π/2 radians. If x is less than -1 or exceeds 1, the arcsine returns NaN (indeterminate value).
Parameters:
x - Value the arcsine of which to be calculated.
Sample:
double x=0.32696, y;
y=MathArcsin(x);
Print("Arcsine of ",x," = ",y);
y=acos(x);
Print("Arccosine of ",x," = ",y);
//Output: Arcsine of 0.326960=0.333085
//Output: Arccosine of 0.326960=1.237711
MathArctan()
double MathArctan(double x)
The MathArctan returns the arctangent of x. If x is 0, MathArctan returns 0. MathArctan returns a value within the range of -π/2 to π/2 radians.
Parameters:
x - A number representing a tangent.
Sample:
double x=-862.42, y;
y=MathArctan(x);
Print("Arctangent of ",x," is ",y);
//Output: Arctangent of -862.42 is -1.5696
MathCeil()
double MathCeil(double x)
The MathCeil function returns a numeric value representing the smallest integer that exceeds or equals to x.
Parameters:
x - Numeric value.
Sample:
double y;
y=MathCeil(2.8);
Print("The ceil of 2.8 is ",y);
y=MathCeil(-2.8);
Print("The ceil of -2.8 is ",y);
/*Output:
The ceil of 2.8 is 3
The ceil of -2.8 is -2*/
MathCos()
double MathCos(double value)
Returns the cosine of the specified angle.
Parameters:
value - An angle measured in radians.
Sample:
double pi=3.1415926535;
double x, y;
x=pi/2;
y=MathSin(x);
Print("MathSin(",x,") = ",y);
y=MathCos(x);
Print("MathCos(",x,") = ",y);
//Output: MathSin(1.5708)=1
// MathCos(1.5708)=0
MathExp()
double MathExp(double d)
Returns the value of e raised to the power of d. At overflow, the function returns INF (infinity), and it returns 0 at underflow.
Parameters:
d - A number specifying the power.
Sample:
double x=2.302585093,y;
y=MathExp(x);
Print("MathExp(",x,") = ",y);
//Output: MathExp(2.3026)=10
MathFloor()
double MathFloor(double x)
The MathFloor function returns a numeric value representing the largest integer that is less than or equal to x.
Parameters:
x - Numeric value.
Sample:
double y;
y=MathFloor(2.8);
Print("The floor of 2.8 is ",y);
y=MathFloor(-2.8);
Print("The floor of -2.8 is ",y);
/*Output:
The floor of 2.8 is 2
The floor of -2.8 is -3*/
MathLog()
double MathLog(double x)
The MathLog function returns the natural logarithm of x if successful. If x is negative, these functions return NaN (indeterminate value). If x is 0, they return INF (infinity).
Parameters:
x - Value logarithm of which to be found.
Sample:
double x=9000.0,y;
y=MathLog(x);
Print("MathLog(",x,") = ", y);
//Output: MathLog(9000)=9.10498
