Question

how can i divide value that has power of 10 in javascript?

For example:

-5x10^-3 * 3x10^-9

is there a way to do this like a

Math.powof(5,-3)

something like that?

Answer 1

Why not use exponent notation?

-5e-3 * 3e-9

which is equivalent to:

-0.005 * 0.000000003;

Note that when dealing with small decimals, javascript arithmatic may not be exact, e.g.

(-5 * Math.pow(10, -3)) * (3 * Math.pow(10,-9)) // -1.5000000000000003e-11

but

-5 * Math.pow(10, -3) * 3 * Math.pow(10,-9)  // -1.5e-11
