MODS


Modulo division of corresponding elements in two dynamic arrays (zero divide not allowed).
Synopsis
MODS(dynarray1,dynarray2)
Arguments
Description
The
MODS function divides the value of each element in
dynarray1 by the corresponding element in
dynarray2. It then returns a dynamic array containing the modulo (remainder) for each element that results from these divisions. If an element is missing or has a null string or a nonnumeric value,
MODS parses its value as 0 (zero).
Attempting to divide by zero generates a <DIVIDE> error, ending execution of the function and invoking an error trap handler, if available. This is the same 0 divisor behavior as the
DIVS function. In contrast, when the corresponding
MODSZ or
DIVSZ functions encounter a 0 divisor, they return 0 for that element.
If the two dynamic arrays have different numbers of elements, the returned dynamic array has the number of elements of the longer dynamic array. By default, the shorter dynamic array is padded with 0 value elements for the purpose of the arithmetic operation. You can also use the
REUSE function to define behavior when specifying two dynamic arrays with different numbers of elements.
You can use the
MOD function or the
REM function to perform modulo division on single values.
You can use the
NUMS function to determine if the elements in a dynamic array are numeric. You can use the
ADDS (addition),
SUBS (subtraction),
MULS (multiplication),
DIVS or
DIVSZ (division), and
PWRS (exponentiation) functions to perform other arithmetic operations on the corresponding elements of two dynamic arrays.
Examples
The following example uses the
MODS function to return the modulo value for each division operation on the elements of two dynamic arrays:
a=11:@VM:22:@VM:0:@VM:7
b=10:@VM:.5:@VM:10:@VM:42
PRINT MODS(a,b); ! returns 1ý0ý0ý7
