Module elementwise 

Elementwise kernels with name-based broadcasting and NumPy type promotion.

Functions

abs

|a|, in the input type. abs(i8::MIN) wraps to i8::MIN, like NumPy.

add

a + b. Integer overflow wraps, like NumPy.

arccos

Inverse cosine, like numpy.arccos.

arcsin

Inverse sine, like numpy.arcsin.

arctan

Inverse tangent, like numpy.arctan.

cast

Cast the values, like ndarray.astype. Keeps the attributes.

cbrt

Cube root, like numpy.cbrt.

ceil

Round up, like numpy.ceil.

clip

Limit values to [min, max], like numpy.clip. Keeps the attributes.

cos

Cosine, like numpy.cos.

cosh

Hyperbolic cosine, like numpy.cosh.

deg2rad

Degrees to radians, like numpy.deg2rad.

div

True division a / b, like numpy.true_divide: integers divide as Float64.

eq

a == b.

exp

e^a, like numpy.exp.

expm1

e^a - 1, like numpy.expm1.

fill_null

Replace nulls with value, a length-1 array. Keeps the attributes.

floor

Round down, like numpy.floor.

floor_divide

Floor division a // b, like numpy.floor_divide. Integer division by zero gives null.

ge

a >= b.

gt

a > b.

is_not_null_mask

true where the value is not null.

is_null_mask

true where the value is null.

isfinite

true where the value is finite, like numpy.isfinite.

isinf

true where the value is infinite, like numpy.isinf.

isnan

true where the value is NaN, like numpy.isnan. Nulls stay null.

le

a <= b.

log

Natural logarithm, like numpy.log.

log2

Base-2 logarithm, like numpy.log2.

log1p

ln(1 + a), like numpy.log1p.

log10

Base-10 logarithm, like numpy.log10.

logical_and

Logical AND with Kleene null logic (false AND null is false).

logical_not

Logical NOT.

logical_or

Logical OR with Kleene null logic (true OR null is true).

logical_xor

Logical XOR. A null input gives a null.

lt

a < b.

map_float

Apply a floating point function. Integers compute as Float64, like NumPy.

mod_

Remainder with the sign of b, like numpy.mod (Python %). Integer division by zero gives null.

mul

a * b. Integer overflow wraps, like NumPy.

nan_to_null

Replace NaN with null, so that NaN counts as missing in all kernels.

ne

a != b.

neg

-a. Integer overflow wraps, like NumPy.

pow

a ** b in floating point, like numpy.float_power.

rad2deg

Radians to degrees, like numpy.rad2deg.

rem

Remainder with the sign of a, like numpy.fmod. Integer division by zero is an error.

result_type

The NumPy result type of two numeric types, like numpy.result_type.

round

Round half to even, like numpy.round with zero decimals.

sin

Sine, like numpy.sin.

sinh

Hyperbolic sine, like numpy.sinh.

sqrt

Square root, like numpy.sqrt.

sub

a - b. Integer overflow wraps, like NumPy.

tan

Tangent, like numpy.tan.

tanh

Hyperbolic tangent, like numpy.tanh.

trunc

Round toward zero, like numpy.trunc.

where_

cond ? x : y, like numpy.where. A null condition picks y. Keeps the attributes of x.
