EXP Function
The EXP function returns the exponent of a numeric expression.
The following example returns the exponent of 3 for each
row of the angles table:
SELECT EXP(3) FROM angles;
For this function, the base is always e, the base
of natural logarithms, as the following example shows:
e=exp(1)=2.718281828459
When you want to use the base of natural logarithms as the base value, use the EXP function. If you want to specify a particular value to raise to a specific power, see the POW Function.
