Element-wise less than comparison. You can also use the < operator.
Arguments
- lhs, rhs
(
arrayish)
Two inputs with a common data type. Can be any data type. Scalars are broadcast. An R value takes the other operand's data type when that is in its own or a higher category. Otherwise it settles on its default data type, and the operands meet at their common data type.- e1, e2
(
arrayish)
The operands of the operator, which it passes on aslhsandrhs.
Value
(arrayish)
Has the inputs' broadcast shape and boolean data type.
See also
prim_lt() for the underlying primitive.
Examples
x <- nv_array(c(1, 2, 3))
y <- nv_array(c(3, 2, 1))
nv_lt(x, y)
#> AnvlArray
#> 1
#> 0
#> 0
#> [ CPUbool{3} ]
x < y
#> AnvlArray
#> 1
#> 0
#> 0
#> [ CPUbool{3} ]
# different data types are promoted to their common one
nv_lt(nv_scalar(1, "f32"), nv_scalar(2, "f64"))
#> AnvlArray
#> 1
#> [ CPUbool{} ]
# a scalar is broadcast and an R integer is converted to a float
x < 2L
#> AnvlArray
#> 1
#> 0
#> 0
#> [ CPUbool{3} ]
