Function | Description | Example | Result |
---|---|---|---|
exp(x) | Returns e raised to the power of x. | exp(1.5) | 4.48 |
exp2(x) | Returns 2 raised to the power of x. | exp2(1.5) | 2.83 |
expm1(x) | Computes the base-e exponential of x , minus 1 accurately even for very small values of x. | expm1(1.5e-5) | 0.0000150001125005625 |
ln(x) | The natural logarithm of x. | ln(1.55) | 0.44 |
log(x, base) | The logarithm of a number to the specified base. | log(255, 2) | 7.99 |
log10(x) | The base_10 logarithm of a number. | log10(405.55) | 2.61 |
log1p(x) | Computes the value of log(1+x) accurately even for very small values of x. | log1p(1.50001125005625e-05) | 1.50E-05 |
log2(x) | The base_2 logarithm of a number. | log2(1.55) | 0.63 |
power(x,y) | Computes x raised to the power y. POWER(x, y) returns the same result as x^y, but using the function will check x and y for possible errors when x <= 0. | power(-1.06, 30) | 5.74 |
