Integer variables

[keikosaito]

Hello again

I was doing some really basic programs for meteorological variables and things related, but I noticed that when I write implicit none and then define my variable that must be integer the value is wrong, because it is rounded down, not rounded to the closest integer value, so when relative humidity must be 80 (real value: 79.999990) it is 79, is there a way to fix it? Thanks in anticipation

Numbers in Fortran truncate towards zero. Try calling NINT on the value.

x = 1.7
y = 2.4
nx = nint(x)
ny = nint(y)
print *, nx, ny

You should get 2 in both cases. There is also AINT, CEILING and FLOOR for rounding in specific directions. Just depends on what your truncation rules are.
