Is there a way to remove all the positive values and print only the negative values, without using grep, sed or awk?
Thanks,

Let, I have three numbers

nextupl
NEXTUP(3) Linux Programmer's Manual NEXTUP(3)NAME
nextup, nextupf, nextupl, nextdown, nextdownf, nextdownl - return next floating-point number toward positive/negative infinity
SYNOPSIS
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <math.h>
double nextup(double x);
float nextupf(float x);
long double nextupl(long double x);
double nextdown(double x);
float nextdownf(float x);
long double nextdownl(long double x);
Link with -lm.
DESCRIPTION
The nextup(), nextupf(), and nextupl() functions return the next representable floating-point number greater than x.
If x is the smallest representable negative number in the corresponding type, these functions return -0. If x is 0, the returned value is
the smallest representable positive number of the corresponding type.
If x is positive infinity, the returned value is positive infinity. If x is negative infinity, the returned value is the largest repre-
sentable finite negative number of the corresponding type.
If x is Nan, the returned value is NaN.
The value returned by nextdown(x) is -nextup(-x), and similarly for the other types.
RETURN VALUE
See DESCRIPTION.
VERSIONS
These functions first appeared in glibc in version 2.24.
