Mantissa in a sentence as a noun

I'd guess 52 of those bits are mantissa.

Also, shifting can cause a least-significant 1 bit from the exponent to shift down into the most significant bit of the mantissa.

Except in the case where the representation of the exponent ended in a 1, in which case that 1 is shifted down into the fractional part of the mantissa.

> Decimal floating point would hardly affect accuracy compared to binary floating pointThe larger the radix, the more of the mantissa is wasted.

The exponent is being effectively divided by 2 and the fractional part of the mantissa is also being effectively divided by 2.
