Library for rounding a number to a quantity of significant figures
Project description
Función signif en Pyhton
Esta función te permite expresar cualquier número real con una determinada cantidad de cifras significativas de forma sencilla. Está inspirada en la función signif de R que realiza la misma tarea y de la cual hereda su nombre.
La función signif(x, n) redondea el valor de su primer argumento x, al número de cifras significativas especificado en su segundo argumento n. Concretamente realiza la operación round(x, n-int(math.floor(math.log10(abs(x))))-1).
El argumento x debe ser de tipo int o float mientras que el argumento n debe ser de tipo int.
