[niccojul]

Hello,

Does anyone know a method to reduce the number of decimals in the answer when multypling with a number with 15 decimals? What I want to achieve an answer with 4 decimals or less.

x * 86,4716007952918 = y,yyyy

X can be any number.

Just round the result to the number of digits you want?
