Wrong assumptions: "double scalbln(double x, long int exp)" and the other implements "x * FLT_RADIX ** exp"; FLT_RADIX usually is 2.

I didn't know the functions "scalbn, scalbnf, scalbnl, scalbln, scalblnf, scalblnl - multiply floating-point number by integral power of radix".

I see that they are not used neither in the standard library neither in the compiler itself which prefer to reimplement it.
Is it perhaps better to use libc in cases like this?
