Function Names
distribute amountDescription
This function distributes an amount provided in the 1st function parameter across a set with number of elements as specified in teh 2nd set. Different options are available to distribut that value: Following rules are supported:
| Rule | Description |
|---|---|
| even | The amount is distributed evenly across all element. Example: 3 over 4 elements result in { 0.75, 0.75, 0.75, 0.75 }. |
| row wise | The amount is distributed as whole numbers across the elements. Example: 14.5 over 4 elements result in { 4, 4, 3.5, 3 }. |
| random | The amount is randomly distributed across the elements. Example: 11.5 over 6 elements could result in { 3, 0, 4, 2.5, 3, 2 }. Note that cases occur where at least one element can stay zero. |
| row wise random | The amount is distributed bottom up across the elements, with the last ones on top distributed evenly. Example: 11.5 over 5 elements could result in { 2, 3, 2, 3.5, 2 }. This function ensures that no two consecutive random values will affect the same set element. |

Parameters
| No. | Type | Description |
|---|---|---|
| 1. input |
numeral | Amount to distribute This amount will be distributed across the set elements so the sum of all elements equals to this amount. |
| 2. input |

|---|---|
| set | Distributed Amount set with the amount distriuted across the elements |
Examples
echo( "even : ", distribute amount( 14, 5, even ) );
echo( "row wise : ", distribute amount( 14, 5, row wise ) );
echo( "row wise random : ", distribute amount( 14, 5, row wise random ) );
echo( "random : ", distribute amount( 14, 5, random ) ); Output
even : {2.8,2.8,2.8,2.8,2.8}
row wise : {3,3,3,3,2}
row wise random : {3,2,3,3,3}
random : {0,1,5,2,6}
