This service re-maps a number from one range to another. That is, a value of fromLow would get mapped to toLow, a value of fromHigh to toHigh, values in-between to values in-between, etc.
fromLow: Number. The lower limit of source range.
fromHigh: Number. The upper limit of source range.
toLow: Number. The lower limit of target range.
toHigh: Number. The upper limit of target range.
in: Number. The input number.
out: Number. The output value.
This service rounds the value of in, and output the result to out.
in: Number. The input number.
out: Number. The output value.
in: 0.5
out is 1
in: 2.4
out is 2
This service generates random number between min and max.
min: Number. The lower limit of random number.
max: Number. The upper limit of random number.
trigger: Any. The event to trigger a generation, value of this inport will be discarded.
out: Number. A random value.
For this example, we will get a random number between [-50, 50] every second.
