Some formula expressions ( such as x / 0 , sqrt(-1) , or log(0) ) calculate values that are undefined in a real number system, infinite, or outside the range supported by Neuron.
When an asset property's expression computes an undefined, infinite, or overflow value, Neuron doesn't output a data point for that computation.
Neuron also doesn't output a data point if it computes a non-numeric value as the result of a formula expression. This means that if you define a formula that computes a string, array, or the none constant, then Neuron doesn't output a data point for that computation.
Examples
Each of the following formula expressions results in a value that Neuron can't represent as a number. Neuron doesn't output a data point when it computes these formula expressions.
x / 0is undefined.log(0)is undefined.sqrt(-1)is undefined in a real number system."hello" + " world"is a string.jp('{"values":[3,6,7]}', '$.values')is an array.if(gte(temp, 100), temp, none)isnonewhentempis less than 100.
