I took a code in fortran 77 where it has a line like this:
DATA ZERO/0D0/,HALF/0.5D0/,ONE/1D0/,TWO/2D0/,THREE/3D0/,FOUR/4D0/
I'm transponder it to PHP. I would like to know what D0 are after assigning the values?
Here - > ZERO / 0 D0 /

DATA ZERO/0D0/,HALF/0.5D0/,ONE/1D0/,TWO/2D0/,THREE/3D0/,FOUR/4D0/
1) It is a concatenated statement in a line, that is, it is the same thing as declaring one by one at a time:
ZERO = 0D0
HALF = 0.5D0
ONE = 1D0
TWO = 2D0
THREE = 3D0
FOUR = 4D0
2) For double precision variables:
See more at: Double Precision in Real Numbers A good example: Double Precision Real (floating point numbers) in Fortran are written in different variations as follows:
