NB: Functions with prototypes containing underscores in type names
may be available only with certain extended compilers.
Compute the product of
x
and the value of
FLT_RADIX
raised to the power
n.
In the absence of underflow and overflow of the result, this scaling
is always
exact.
A companion function, pscalbln(result, x, n), provides for a
higher-precision exponent.
None. The function result is stored in the first argument, result.
None.
