[Release] Simple Math Commands

[Yamato]

Hello

This are some basic math operations and values which arent in game, I can make more if you find them useful,

Code:

e()
{
    return ( 2.71828 );
}

pi()
{
    return ( 3.14159 );
}

radToDegrees( rad )
{
    return ( ( 180 * rad ) / 3.14159 );
}

degreesToRad( degrees )
{
    return ( ( degrees * 3.14159 ) / 180 );
}

power( number, exp )
{
    numberused = number;
    for ( i = 1; i < exp; i++ )
        numberused *= number;
    return numberused;
}

cotan( angle )
{
    return ( cos( angle ) / sin( angle ) );
}

sec( angle )
{
    return ( 1 / cos( angle ) );
}

cosec( angle )
{
    return ( 1 / sin( angle ) );
}

versin( angle )
{
    return ( 1 - cos( angle ) );
}

ValueIsBeetween(value,max,min) //new
{
    if(value > min && value < max)
        return true;
    return false;
}

bisection( angle1, angle2 )
{
    return ( ( angle1 + angle2 ) / 2 );
}

pointsAreInLine( point1, point2, point3 )
{
    if( ( ( point2[0] - point1[0] ) / ( point3[0] - point1[0] ) ) == ( ( point2[1] - point1[1] ) / ( point3[1] - point1[1] ) ) && ( ( point2[0] - point1[0] ) / ( point3[0] - point1[0] ) ) == ( ( point2[2] - point1[2] ) / ( point3[2] - point1[2] ) ) )
        return true;
    return false;
}

areParallel( vector1, vector2 )
{
    if( ( vector1[0] / vector2[0] ) == ( vector1[1] / vector2[1] ) && ( vector1[0] / vector2[0] ) == ( vector1[2] / vector2[2] ) )
        return true;
    return false;
}

vectorScale( vector, scale ) //new
{
    vec = ( vector[0] * scale, vector[1] * scale, vector[2] * scale );
    return vec;
}

vectorDivision( vector, number ) //new
{
    vec = ( vector[0] / number, vector[1] / number, vector[2] / number );
    return vec;
}

vectorModule( vector )
{
    return ( sqrt( ( vector[0] * vector[0] ) + ( vector[1] * vector[1] ) + ( vector[2] * vector[2] ) ) );
}

vectorsAngle( vector1, vector2 ) //new
{
    return acos( vectorDot( vector1, vector2 ) / ( vectorModule( vector1 ) * vectorModule( vector2 ) ) );
}

vectorTo2D( vector ) //new
{
    return ( vector[0], vector[1], 0 );
}

Thanks to:
@iAegle for detecting an error.
@SuperNovaAO for a suggestion.

Hello

This are some basic math operations and values which arent in game, I can make more if you find them useful,

Code:

...

exp( number, exp )
{
    numberused = number;
    for ( i = 1; i < exp; i++ )
        numberused *= number;
    return numberused;
}

...

Code:

exp( number, exp )
{
return number ^ exp;
}

I guess these could help someone though lol

Does this work?

Code:

return number ^ exp;

Usually in programming the exp function calculates e ^ number

pow would be the power then

I have put power, , I dont understand very well what you mean by pow.

You edited it you troll. Your power function was first called exp which is confusing.

Yes, exactly, it was called exp and now is called power, I changed it when I saw your post.

nice yamato, sound cool

[Yamato]

I added a few more.

One note, the new ones havent been tested, . My mw2 doesnt work.

[Yamato]

I made this other ones sometime ago, but I could never test them (and @Rendflex seems dead ), if anyone can give them a try, say here if they work or not
