The EXP function raises the value "e" (approximately 2.72) to a specified power. This function is the inverse of the LOG function, which returns the logarithm of the argument.
EXP calculates the result by adding terms of an infinite series. If a term adds less than .000001 percent to the sum, the function ends the calculation and returns the result as a double-precision number.
Is the power to which "e" is raised.
Is the name of the field that contains the result, or the format of the output value enclosed in single quotation marks.
EXP raises "e" to the power designated by the &POW variable, specified here as 3. The result is then rounded to the nearest integer with the .5 rounding constant and returned to the variable &RESULT. The format of the output value is D15.3.
-SET &POW = '3'; -SET &RESULT = EXP(&POW, 'D15.3') + 0.5;-HTMLFORM BEGIN <HTML> <BODY> E TO THE &POW POWER IS APPROXIMATELY &RESULT </BODY> </HTML> -HTMLFORM END
The output is:
E TO THE 3 POWER IS APPROXIMATELY 20
