The reason David’s advice is correct is that decimal numbers on computers are represented as binaries and are fundamentally inaccurate: it is not possible to exactly represent 0.1 in binary, just as it’s impossible to exactly represent 1/3 as a decimal fraction.You avoid the representation problem by letting GnuCash compute the price for you.
If you really insist on entering the price, enter it as a rational number... but it must be exactly correct or GnuCash will change it, and that means exactly correct after rounding the value to the smallest currency unit (1/100 in most currencies). E.g., you can’t buy 100 shares at $1.23456 because $123.456 is nonsensical: It’s either $123.45 or $123.46.
