+.SH DESCRIPTION
+These functions multiply their first argument
+.I x
+by FLT_RADIX (probably 2) to the power
+.IR exp .
+
+If FLT_RADIX equals 2, then
+.B scalbn()
+is equivalent to
+.BR ldexp() .
+
+The value of FLT_RADIX is found in
+.I <float.h>.
+.\" not in /usr/include but in a gcc lib
+.SH "CONFORMING TO"
+The
+.B scalb()
+function is from BSD 4.3.
+The
+.B scalbn()
+and
+.B scalbln()
+functions are from C99.
+All three are in POSIX 1003.1-2003. The
+.B scalb()
+function is marked obsolescent.
