the decimal point. SAS will insert a decimal point only if it does not encounter a decimal point in the specified w columns. Therefore, we could have coded the informat as 8. or 8.2. How come 8. and 8.2 are the
除了data步和proc步,SAS还包含全局语句(In addition to DATA and PROC steps, a SAS program can also contain global statements. );全局语句后面不需要run(Global statements do not need a run statement after them.)例如:titles...; options...; libname... 间距空格对SAS来说不重要(spacing doesn't ma...

All irrational or repeating decimals have such an issue and never fit exactly. 1/3 is 0.3333333333333333 (until you get tired of typing 3 and it still goes on). So if that is your need then controlling the result of your calculations by rounding, truncating or other approach may...

By default SAS will attempt to use that format if it will fit and the axis has space, so if you have a format like F15.12 that could explain the decimals since you apparently have few records involved. When odd things happen, i.e. you ask questions about them, it is best to copy ...
