Return the result of multiplying the specified `value` by ten raised to the specified `exponent`. The quantum of `value` is scaled according to IEEE 754's `scaleB` operations.

scaleB(

    int exponent);

== Description

Special value handling: * If `value` is quiet NaN, quiet NaN is returned. * If `value` is signaling NaN, quiet NaN is returned and the value of the macro `EDOM` is stored into `errno`. * If `x` is infinite, then infinity is returned. * If a range error due to overflow occurs, infinity is returned and: the value of the macro `ERANGE` is stored into `errno`.
