The use of "mantissa"[1] in this document is not right. What's being called mantissa here should be "exponent". There's some ambiguity about what exactly "mantissa" means in the representation of a floating point number, to the point where some people recommend avoiding it[2] (for example, the IEEE standard for floating point uses "significand" instead). But whatever mantissa means, it's exactly not (like the page says[1]) what's "used to raise or lower a floating point literal numbers by factors of 10", that's the exponent. The mantissa, if anything, is the other part of the number, that is, what's being multiplied by the factors of 10 (but it's complicated, the wikipedia[2] page explains it).
