  16. def requiredBitsForSInt(num: BigInt): Int

    return the smallest number of bits required to hold the given number in an SInt Note: positive numbers will get one minimum width one higher than would be required for a UInt

    return the smallest number of bits required to hold the given number in an SInt Note: positive numbers will get one minimum width one higher than would be required for a UInt

    num

    returns

    minimum required bits for an SInt
