Class SubtractTask

This task will subtract a numerical input by a scalar value from a job of subtasks, an aggregator, or a big.

Input: The current running numerical result output from a scalar value, an aggregator, a job of subtasks or a big.

Returns: A numerical result.

Example: Returns the numerical result by subtracting by a job of subtasks.

{"tasks":[{"valueTask":{"value":100}},{"subtractTask":{"job":{"tasks":[{"valueTask":{"value":10}}]}}}]}

Example: Returns the numerical result by multiplying by an aggregator.

{"tasks":[{"valueTask":{"value":100}},{"subtractTask":{"aggregatorPubkey":"GvDMxPzN1sCj7L26YDK2HnMRXEQmQ2aemov8YBtPS7vR"}}]}

Example: Returns the numerical result by multiplying by a big.

{"tasks":[{"cacheTask":{"cacheItems":[{"variableName":"TEN","job":{"tasks":[{"valueTask":{"value":10}}]}}]}},{"valueTask":{"value":100}},{"subtractTask":{"big":"${TEN}"}}]}
