IFS OI Server provides functions for performing several common mathematical calculations. The functions all require the same parameters and are used in the same way, but produce a result relevant to the function.
Functions
| Format | Returns |
| Cos(Number) | Returns the cosine of Number, which is an angle expressed in radians. |
| Sin(Number) | Returns the sine of Number, which is an angle expressed in radians. |
| Tan(Number) | Returns the tangent of Number, which is an angle expressed in radians. |
| ArcCos(Number) | Returns the inverse cosine of Number, which is an angle expressed in radians. |
| ArcSin(Number) | Returns the inverse sine of Number, which is an angle expressed in radians. |
| ArcTan(Number) | Returns the inverse tangent of Number, which is an angle expressed in radians. |
| Log(Number) | Returns the natural logarithm of Number. |
| Log10(Number) | Returns the logarithm to base 10 of Number. |
| Abs(Number) | Returns the absolute value of Number. |
| Exp(Number) | Returns the exponential of Number. That is, e (approximately 2.72) raised to the power of EXPR. |
| Sqrt(Number) | Returns the square root of Number. If EXPR is negative, an error is produced. |
| Fix(Number) | Returns the integer portion of Number. For negative numbers, the less negative integer (closer to zero) will be returned. |
