How can i round the digits of a number?

[ledi001]

Hi,

i am new with node-red functionality and i want to decrease the digits in a Gauge.

When i start the Dashboard i get the temperature in e.g. 21.77615442345 degrees. And i want to show it with 2 digits e.g. 21.78 degrees.

Ho can i do this?

What produces the printout. Maybe some format string like %6.3f will help.

got it... :)

in the Gauge-node (Value format) type in {{value | number:2}}

will round the value by 2 digits.
