Number of Significant Figures in Result of Multiplication/Examples/8.416 x 50

Example of Use of Number of Significant Figures in Result of Multiplication

 * $8 \cdotp 416 \times 50 = 420 \cdotp 8$

on the assumption that $50$ is exact.

Proof
We have that:
 * the number of significant figures $d_m$ in $8 \cdotp 416$ is $4$
 * the number of significant figures $d_n$ in $50$ is unlimited

So from Number of Significant Figures in Result of Multiplication:


 * the number of significant figures in $8 \cdotp 416 \times 50$ can be no more than $\min \set {4, \infty}$, that is $4$.
