abs, sign, ceil, floor, trunc, frac - Numerical Functions
The following table shows the general numerical functions for a single unnamed argument with any numerical data type. These functions are overloaded with the effect that the return value can have different numerical types
abs, sign, ceil, floor, trunc, frac
| Functionfunc | Return value |
| abs | Absolute value of argument arg |
| sign | Sign of argument arg: -1, if the value of arg is negative; 0, if the value of arg is 0; 1, if the value of arg is positive |
| ceil | Smallest integer that is not less than the value of the argument arg is |
| floor | Largest integer that is not greater than the value of the argument arg is |
| trunc | Value of the integer part of the argument arg |
| frac | Value of the decimal places of the argument arg |
