# LET

Assigns names to calculation results. This allows storing intermediate calculations, values, or defining names inside a formula. These names only apply within the scope of the LET function.

### Sintaxia

=LET(Name1; Name_value1; Calculation_or_Name2 [; Name_value2; Calculation_or_Name3 [; ...]])

Name1: the first name to assign. Must start with a letter. Cannot be the output of a formula or conflict with range syntax.

Name1 must follow the naming rules of LibreOffice Calc.

Name_value1: the value or calculation to assign to Name1.

Name2; Name_value2;...: (optional) same as Name1 and Name_value1, respectively. Name_value2 must follow Name2 and so on.

Calculation: a formula expression that uses all names within the LET function.

Calculation must be the last argument in the LET function.

Demagun datu-base txiki bat eraiki dugula A1:DO4 gelaxka-barrutian, eta datu-base horrek 118 elementu kimikori buruzko informazioa duela. Lehen zutabeak 'Elementua', 'Ikurra', 'Zenbaki atomikoa' eta 'Masa atomiko erlatiboa' errenkada-izenburuak ditu. Gainerako zutabeek elementu bakoitzaren informazioa dute, eta elementuak ezkerretik eskuinera ordenatuta daude zenbaki atomikoaren arabera. Adibidez, B1:B4 gelaxkek 'Hidrogenoa', 'H', '1' eta '1.008' balioak dituzte, eta DPO1:DO4 gelazkek 'Oganesona', 'Og', '118' eta '294' balioak dituzte.

Calculate the molar mass of the water molecule knowing that the molecule has 2 hydrogen atoms and one oxygen atom.

=LET(mHydro; HLOOKUP("Hydrogen"; $A$1:$DO$4; 4; 0); mOxy; HLOOKUP("Oxygen"; $A$1:$DO$4; 4; 0); "The molar mass of water is "&(mOxy+2*mHydro)&" g/mol") returns "The molar mass of water is 18.015 g/mol".
