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.
Syntax
... func( arg ) ...
Effect
The argument of a general numerical function must be an individual data object outside an arithmetic expression, and can itself be a numeric expression within an arithmetic expression.
Effect of the general numerical functions.
Function func | 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 |
The following applies with regard to the data type of the return value:
If the argument of a numerical function outside of an arithmetic expression has no numerical data type, i, p, decfloat16, decfloat34, or f its data type determines the type of return value as follows:
Before the calculation of the function, the argument is converted into the respective type..
Note
The functions described here are some of the functions that can be used in the obsolete extended functional operand positions, even if their argument is a single data object.
