Description:
ca: >-
<p>El Qalculate! és una calculadora d'escriptori per a diverses plataformes i finalitats. És senzill a usar però proporciona
poder i versatilitat que normalment es reserva als paquets de matemàtica complicats, així com eines útils per a necessitats
diàries (com la conversió de monedes i calculació de percentatge).</p>
<p>Les característiques inclouen una biblioteca amplia de funcions personalitzables, calculació i conversió d'unitat,
constants físics, càlculs simbòlics (incloent integrals i equacions), precisió arbitrària, propagació d'incertesa, aritmètica
d'interval, dibuix i una interfície fàcil d'emprar.</p>
