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
