Formulas

💡 Note that trigonometric functions (sin(), cos(), tan(), asin(), acos(), atan(), atan2()) expect (and return) angles in radians. To convert radians to degrees, divide by (Math.PI / 180). Multiply by the same value to convert degrees to radians.

💡 Many Math functions have a precision that's implementation-dependent. This means that different OS can give a different result.

Math.roundDecimal(x;precision;roundType)

    This method can be used to round a value.

    x (real) : number to round
    precision (real) : The precision of the value that we want to round. Ex. 0.1, 0.5, 2, 0.01
    roundType (String) : The list of existing round type must use one of those constants:

    ROUND_UP : Round UP away from 0 (<-0->)
    ROUND_DOWN : Round DOWN toward 0 (->0<-)
    ROUND_CEILING : Round UP (<-0<-)
    ROUND_FLOOR : Round DOWN (->0->)
