To much decimals in a value template with 2 sensors

Configuration

Can someone help me with this:

value_template: "{{ (states('sensor.monthly_energy_peak')|float * 0.31) | round(2) + (states('sensor.monthly_energy_offpeak')|float * 0.23) | round(2) }}"

and this is the result:

round after the calculation, not during.

value_template: "{{ (states('sensor.monthly_energy_peak') | float * 0.31  + states('sensor.monthly_energy_offpeak') | float * 0.23) | round(2) }}"

Thanks Petro!
