floor¶
- floor(x: array, /) array ¶
Rounds each element
x_i
of the input arrayx
to the greatest (i.e., closest to+infinity
) integer-valued number that is not greater thanx_i
.- Parameters:
x (array) – input array. Should have a real-valued data type.
- Returns:
out (array) – an array containing the rounded result for each element in
x
. The returned array must have the same data type asx
.
Notes
Special cases
If
x_i
is already integer-valued, the result isx_i
.
For floating-point operands,
If
x_i
is+infinity
, the result is+infinity
.If
x_i
is-infinity
, the result is-infinity
.If
x_i
is+0
, the result is+0
.If
x_i
is-0
, the result is-0
.If
x_i
isNaN
, the result isNaN
.
