The EXP math function returns the value of e to the power of the parameter used.


value = EXP(exponent)

  • e is defined as the base of natural logarithms or as the limit of (1 + 1 / n) ^ n as n goes to infinity
  • The exponent value MUST be less than or equal to 88.02969 or an "overflow" error will occur!
  • Value returned is e to the exponent parameter. e = 2.718282 (approximately)
  • Values returned are SINGLE by default but will return DOUBLE precision if the exponent uses a double value.
  • Positive exponent values indicate the number of times to multiply e by itself.
  • Negative exponent values indicate the number of times to divide by e. Example: e-3 = 1 / e3 = 1 /(e * e * e)
