![]() ![]() The decimal may be shifted by the "BEST" format. NOTE: At least one W.D format was too small for the number to be printed. ![]() NOTE: The data set WORK.TEST has 1 observations and 3 variables. The INPUT() function does not care if the informat width is larger than the length of the string being read, so just go ahead and use the maximum width the informat allows.Ģ length CharVar $50 value_num1 value_num2 8 ĥ Value_num2 = input(translate(charvar,'.','.,'),32.) When you use BEST as an informat without a width it will default to only 12 characters. Also how SAS has to switch from your requested 20.14 display format since that only leaves room for 5 digits before the decimal point.Īlso informats, like formats, have a defined default width they will use when none is specified. Here are some examples of things you may want to do. Converting values from/to character and numeric values is one of the most common operations in SAS. Convert char to numeric Convert numeric to char. So notice how there is only room to represent 5 of the 13 digits your value has after the decimal point given the 10 digits that it has before the decimal point. SAS Examples: Numeric/Character Conversions Last updated. So SAS can only exactly represent 15 decimal digits. The largest contiguous integer value that can be represented exactly in the IEEE format used in Windows and UNIX implementations of SAS is 9,007,199,254,740,992. So just use: data want set have newMAGE input (MAGE, 32.) run If the values in MAGE have thousands separators then you might want to use the COMMA. The INPUT () function does not care if you use a width on the informat specification that is larger than the length of the string being read. SAS integration with Redshift Heres a simple query to illustrate how to. For most values try the normal numeric informat. SAS stores all numbers as 64 bit floating point values. of built-in Redshift data types: Character, Numeric, Datetime and Boolean. If you actually have 19 significant decimal digits your request to use 20.14 display format suggests then you will lose precision by converting to numbers. When you use BEST as an informat it is just an alias for the normal numeric informat. Note that BEST is the name of a format not an informat. If the values also include periods as thousand separators then use the COMMAX informat instead. To read a value that is using comma as the decimal point indicator instead of the normal period you can use the NUMX informat. Which is explained here and here : the compiler detects different types for variable and format, assumes it's a mistake, add the presumed-missingĪll these trials would work if I created a second variable like for example :īut I'm trying to clean up my code and I wonder if there is a way to do such a conversion without doing so ? NOTE: Numeric values have been converted to character values at the places given by: (Line):(Column).ĮRROR 48-59: The informat $BEST was not found or could not be loaded. NOTE: Character values have been converted to numeric values at the places given by: (Line):(Column). When SAS performs this implicit numeric to character conversion it must select the format to use when performing the conversion and the width of the converted string. ![]()
