Showing answer as 0.0 when multiplying 1E-9 by 1000

[Alpha2020]

I am developing an app in which I have a simple multiplication of the number 0.000000001 by 1000. But when I do it it is showing the result as 0.0 instead of 0.000001. Is there any way to prevent this.

I was further exploring this issue and I noticed same issue for the following numbers also is giving 0.0 as the result-
0.000000001 * 1000 = 0.0 (expected correct result: 0.000001)
0.000000002 * 1000 = 0.0 (expected correct result: 0.000002)
0.000000003 * 1000 = 0.0 (expected correct result: 0.000003)
0.000000004 * 1000 = 0.0 (expected correct result: 0.000004)
0.000000005 * 1000 = 0.0 (expected correct result: 0.000005)

0.000000006 * 1000 = 0.00001 (Looks like the answer is rounded). (expected correct result: 0.000006)
0.000000007 * 1000 = 0.00001 (Looks like the answer is rounded) (expected correct result: 0.000007)
0.000000008 * 1000 = 0.00001 (Looks like the answer is rounded) (expected correct result: 0.000008)
0.000000009 * 1000 = 0.00001 (Looks like the answer is rounded) (expected correct result: 0.000009)

0.00000001 * 1000 = 0.00001 (This result is showing correctly)

use the format as decimal block

It is similar to what it is in scratch most likely that the program is reading only a particular amount of digits when not formatted, as @Taifun said, you should use the format as decimal block.
