Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

 EXP(numeric-expression)
 LOG(numeric-expression)
 
 Usage Notes
   ■ EXP and LOG are calculated in single precision if numeric-expression
     is an integer or a single-precision value. If you use any other numeric
     data type, EXP and LOG are calculated in double precision.
 
   ■ The valid range for EXP numeric expressions is <= 88.02969 (single-
     precision) or <= 709.782712893 (double-precision). If numeric-expression
     is outside the valid range, Visual Basic generates the run-time error
     message, "Overflow."
 
  ■ The constant e is approximately equal to 2.718282.
 
   ■ The natural logarithm is the logarithm to the base e.
 
   ■ You can calculate base-n logarithms for any number x by dividing the
     natural logarithm of x by the natural logarithm of n:
 
         LOGn = LOG(x)/LOGn
 
     For example, the following FUNCTION procedure calculates base-10
     logarithms:
 
         FUNCTION LOG10(X) STATIC
             LOG10 = LOG(X)/LOG(10)
         END FUNCTION
