Logarithms
Function | Name | Behaviour |
exp() | Exponential | Calculates the value of e to the power of x, where e is the base of the natural logarithm. exp(1) returns Euler's number. |
ln() | Natural logarithm | The natural logarithm of a number is its logarithm to the base of the mathematical constant e. |
log2() | Base 2 logarithm | Calculate the base 2 logarithm of a value |
log(), log10() | Base 10 logarithm | Calculate the base 10 logarithm of a value |

Trigonometric functions assume a value in radians by default.
If you want to use degrees, specify this in the parameter:
sin(90 degrees) = 1.0
sin(90) = 0.8939966636
Inverse trigonometry functions
Function | Name |
asin() | Calculate the inverse sine of a value |
acos() | Calculate the inverse cosine of a value |
atan() | Calculate the inverse tangent of a value |
Inverse trigonometric functions return a value in radians. If you want to use degrees, specify this in the parameter:
asin(0.5 degrees) = 30º
asin(0.5) = 0.5235988 radians
