  1. Feb 27, 2014 #1
    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.

    Best regards,

    Nicolai

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