MathFloor double (double x)

MathFloor The function returns a numeric value represents the largest number that is less than or equal to x.
Parameters

Sample
double y;
y = MathFloor (2,8);
Print ("The floor is 2,8", y);
y = MathFloor (-2.8);
Print ("The floor of -2.8 is", y);
/ * Output:
The floor is of 2.8 2
The floor of -2.8 is -3 * /


MathLog double (double x)

The functions return MathLog logarithm of x if successful. If x is negative, these functions return an indefinite (same as quiet Nan). If x is 0, they return INF (infinite).
Parameters

x - value whose logarithm can be found.
Sample
double x = 9000,0, y;
y = MathLog (x);
Print ("MathLog (" x ") =", y);

void MathSrand (int seed)

The MathSrand () function sets the starting point for generating a series of pseudorandom integers. To reinitialize the generator, use 1 as the seed argument.
