amounts in value reports can sometimes be shown unstyled / with zero decimal digits

This is a potentially surprising behaviour noted in hledger manual > More valuation examples, circa version 1.31.

Here, A's value in B is 0.5B, and a valued print report shows it as expected:

P 2023-01-01 A 0.5B

2023-01-01
  a    1A
  b

$ hledger-1.31 print -X B
2023-01-01
    a            0.5B
    b           -0.5B

Here is the same transaction, but this time the rate is inferred
by reversing the declared B to A price, and there's no B amount
written in the journal from which to infer a display precision,
so B is displayed with the default style (symbol on the left)
and precision (0 decimal digits).
(Also, because the displayed amount looks like zero, no minus sign
is displayed, and before 1.30 the symbol was not displayed either.)

P 2023-01-01 B 2A

2023-01-01
  a  1A
  b

$ hledger-1.31 print -X B
2023-01-01
    a              B0
    b              B0

Other reports are similarly affected:

$ hledger-1.31 bal -E -X B
                   0  a
                   0  b
--------------------
                   0
