To avoid the note being written to the log, you can explicitly perform the character to numeric conversion. NOTE: Character values have been converted to numeric values at the places given by: Here the character variable “75″ is converted to a numeric variable and the statement executes giving the expected result, but writing a NOTE to the log explaining that SAS has had to perform an implicit conversion in order for the calculation to take place. SAS automatically converts the variable from character to numeric so that the calculation can take place). In this instance SAS will perform an implicit conversion (i.e. A character variable WEIGHT_KG is created and assigned the value “75″, the subsequent statement attempts to use this character variable in a numeric calculation. Here we look at a few example where this implicit conversion is performed and look at ways in which the programs can be updated to avoid the NOTE.Ĭonsider for example the following DATA step. Implicit conversions also take more CPU time than explicit conversions and so may cause your program to execute more slowly. It is possible to rely on SAS to perform these conversions imlpicitly, however, in general this is not considered good programming practice and it is usually preferable to perform these conversions explicitly.

This message occurs when you try to perform a numeric calculation using a character variable, or to assign a character value to a variable which has already been defined as numeric.
CONVERT CHARACTER TO NUMERIC SAS HOW TO
In the last two posts we looked at how to clean the log by removing SAS NOTEs, here we look again at what to do when your log contains the following message: NOTE: Character values have been converted to numeric values.
