Hello Experts,

Is there any inbuild FLOOR function to do FLOOR func in mathmetics in awk script like in FlOOR Func in C.

Ex:- floor(2.9) = 2
floor(2.1) = 2
floor(2.0) = 2
floor(-2.0) = 2
floor(-2.1) = -3
floor(-2.9) = -3

If there does not exist in awk script please help me some tricks to do it ...

Thanks in advance..
