Description

The following arithmetic functions do not support decimal:

• abs
• abs_checked
• acos
• acos_checked
• asin
• asin_checked
• atan
• ceil
• cos
• cos_checked
• floor
• is_finite
• is_inf
• is_nan
• ln
• ln_checked
• log1p
• log1p_checked
• log2
• log2_checked
• logb (float/decimal works int/decimal does not)
• logb_checked (float/decimal works int/decimal does not)
• mode
• negate
• negate_checked
• power (float/decimal works int/decimal does not)
• power_checked (float/decimal works int/decimal does not)
• quantile
• round (ARROW-13975)
• round_to_multiple (ARROW-13975)
• sign
• sin
• sin_checked
• stddev
• tan
• tan_checked
• tdigest
• trunc
• variance

? - May not be applicable

The following kernels arithmetic functions do support decimal inputs

• add

• less (ARROW-13966)
• less_equal (ARROW-13966)
• mean
• min_max
• multiply
• multiply_checked
• product
• subtract
• subtract_checked
• sum
• unique
