Modifier to apply to the field value

Defaults to none

Variants

None

Do not apply any multiplier to the field value

Log

Take the common logarithm of the field value

Because this function will return a negative value and cause an error if used on values between 0 and 1, it is recommended to use log1p instead.

Log1P

Add 1 to the field value and take the common logarithm

Log2P

Add 2 to the field value and take the common logarithm

Ln

Take the natural logarithm of the field value.

Because this function will return a negative value and cause an error if used on values between 0 and 1, it is recommended to use ln1p instead.

Ln1P

Add 1 to the field value and take the natural logarithm

Ln2P

Add 2 to the field value and take the natural logarithm

Square

Square the field value (multiply it by itself)

Sqrt

Take the square root of the field value

Reciprocal

Reciprocate the field value, same as 1/x where x is the field’s value
