Subject: [PATCH] Fixing precision issue when converting the u64 cents amount
into f32. (clients/rust/gcli-v2s!39)
* Fixing precision issue when converting the u64 cents amount into f32.
Now composing the displayed value with integer part and fractional part separately (keeping left padding of 0 for the decimal part for the amount of decimals required)
