Hello guys. I want to save the numbers between 0 and 1 with 0.01 increasement to a dat file. I wrote a code for this using Fortran however, after a point I get 0.314999 instead of 0.315000. Can you help me to solve my problem?(adsbygoogle = window.adsbygoogle || []).push({});

<code>

REAL, DIMENSION(:), ALLOCATABLE :: Y

REAL STEP, JEND, PX, GR, RE, RATIO

INTEGER N, I, J

JEND = 1.00

STEP = 1E-3

N = JEND/STEP+1

RE=1

GR=1

RATIO=GR/RE

PX=-12.00

ALLOCATE (Y(N))

Y(1) = 0.0

OPEN(UNIT=8, FILE='HEATLINE.DAT', STATUS='OLD', FORM='FORMATTED')

DO I = 2, N

Y(I) = Y(I-1)+STEP

END DO

PRINT *, 'N IS:' , N

PRINT *, 'I IS:',I

53 format('VARIABLES = "Y"')

WRITE(8,53)

do i=1,n

write(8,*) Y(I)

end do

CLOSE(8)

END
