+.SH DESCRIPTION
+These functions return the result of multiplying the floating-point number
+.I x
+by 2 raised to the power
+.IR exp .
+.SH RETURN VALUE
+On success, these functions return
+.IR "x * (2\[ha]exp)" .
+.P
+If
+.I exp
+is zero, then
+.I x
+is returned.
+.P
+If
+.I x
+is a NaN,
+a NaN is returned.
+.P
+If
+.I x
+is positive infinity (negative infinity),
+positive infinity (negative infinity) is returned.
+.P
+If the result underflows,
+a range error occurs,
+and zero is returned.
+.P
+If the result overflows,
+a range error occurs,
+and the functions return
+.BR HUGE_VAL ,
+.BR HUGE_VALF ,
+or
+.BR HUGE_VALL ,
+respectively, with a sign the same as
+.IR x .
+.SH ERRORS
+See
+.BR math_error (7)
+for information on how to determine whether an error has occurred
+when calling these functions.
+.P
+The following errors can occur:
+.TP
+Range error, overflow
+.I errno
+is set to
+.BR ERANGE .
+An overflow floating-point exception
+.RB ( FE_OVERFLOW )
+is raised.
+.TP
+Range error, underflow
+.I errno
+is set to
+.BR ERANGE .
+An underflow floating-point exception
+.RB ( FE_UNDERFLOW )
+is raised.
