-.SH DESCRIPTION
-These functions return the (real) cube root of
-.IR x .
-This function cannot fail;
-every representable real value
-has a real cube root,
-and rounding it to a representable value
-never causes overflow nor underflow.
-.SH RETURN VALUE
-These functions return the cube root of
-.IR x .
-.P
-If
-.I x
-is +0, \-0, positive infinity, negative infinity, or NaN,
-.I x
-is returned.
-.SH ERRORS
-No errors occur.
