Prototype Methods
| abs |
Returns the absolute value of its argument. |
| acos |
Returns an approximation to the arc cosine of the argument. The argument is expressed in radians. |
| asin |
Returns an approximation to the arc sine of the argument. The argument is expressed in radians. |
| atan |
Returns an approximation to the arc tangent of the argument. The argument is expressed in radians. |
| atan2 |
Returns an approximation to the arc tangent of (x/y),
where the signs of the arguments are used
to determine the quadrant of the result. The
arguments are expressed in radians. |
| ceil |
Returns the smallest integer value that is not less than the argument. If the argument is already an integer, the result is the argument itself. |
| cos |
Returns an approximation to the cosine of the argument. The argument is expressed in radians. |
| exp |
Returns an approximation to the exponential function of the argument (e raised to the power of the argument, where e is the base of the natural logarithms). |
| floor |
Returns the greatest integer value that is not greater than the argument. If the argument is already an integer, the result is the argument itself. |
| log |
Returns an approximation to natural logarithm of the argument. |
| max |
Returns the larger of the two arguments. |
| min |
Returns the smaller of the two arguments. |
| pow |
Returns an approximation to the result of raising x to the power of y. |
| random |
Returns a pseudo-random decimal value in the range of zero to one. The random number generator is seeded with the current system time. |
| round |
Returns the integer value that is closest to the argument. |
| sin |
Returns an approximation to the sine of the argument. The argument is expressed in radians. |
| sqrt |
Returns an approximation to the square root of the argument. |
| tan |
Returns an approximation to the tangent of the argument. The argument is expressed in radians. |
