Say I want to define a macro variable "num" to be 10 to the negative 2 power (0.01). I do:
%let num=%eval(10**(-2));
%put &num.;
but I get
%put &num.;
SYMBOLGEN: Macro variable NUM resolves to 0
0
What's wrong here? Thanks.
To work with floating point numbers use %SYSEVALF().
The %EVAL function evaluates expressions using integer arithmetic. The %SYSEVALF function evaluates expressions using floating point arithmetic.
%let num=%sysevalf(10**(-2));
%put &num.;
