__mod__

array.__mod__(other: int | float | array, /) → array

Evaluates self_i % other_i for each element of an array instance with the respective element of the array other.

Note

For input arrays which promote to an integer data type, the result of division by zero is unspecified and thus implementation-defined.

Special Cases

Note

In general, this method is not recommended for floating-point operands as semantics do not follow IEEE 754. That this method is specified to accept floating-point operands is primarily for reasons of backward compatibility.

For floating-point operands, let self equal x1 and other equal x2.

  • If either x1_i or x2_i is NaN, the result is NaN.

  • If x1_i is either +infinity or -infinity and x2_i is either +infinity or -infinity, the result is NaN.

  • If x1_i is either +0 or -0 and x2_i is either +0 or -0, the result is NaN.

  • If x1_i is +0 and x2_i is greater than 0, the result is +0.

  • If x1_i is -0 and x2_i is greater than 0, the result is +0.

  • If x1_i is +0 and x2_i is less than 0, the result is -0.

  • If x1_i is -0 and x2_i is less than 0, the result is -0.

  • If x1_i is greater than 0 and x2_i is +0, the result is NaN.

  • If x1_i is greater than 0 and x2_i is -0, the result is NaN.

  • If x1_i is less than 0 and x2_i is +0, the result is NaN.

  • If x1_i is less than 0 and x2_i is -0, the result is NaN.

  • If x1_i is +infinity and x2_i is a positive (i.e., greater than 0) finite number, the result is NaN.

  • If x1_i is +infinity and x2_i is a negative (i.e., less than 0) finite number, the result is NaN.

  • If x1_i is -infinity and x2_i is a positive (i.e., greater than 0) finite number, the result is NaN.

  • If x1_i is -infinity and x2_i is a negative (i.e., less than 0) finite number, the result is NaN.

  • If x1_i is a positive (i.e., greater than 0) finite number and x2_i is +infinity, the result is x1_i. (note: this result matches Python behavior.)

  • If x1_i is a positive (i.e., greater than 0) finite number and x2_i is -infinity, the result is x2_i. (note: this result matches Python behavior.)

  • If x1_i is a negative (i.e., less than 0) finite number and x2_i is +infinity, the result is x2_i. (note: this results matches Python behavior.)

  • If x1_i is a negative (i.e., less than 0) finite number and x2_i is -infinity, the result is x1_i. (note: this result matches Python behavior.)

  • In the remaining cases, the result must match that of the Python % operator.

Parameters:

  • self (array) – array instance. Should have a numeric data type.

  • other (Union[int, float, array]) – other array. Must be compatible with self (see Broadcasting). Should have a numeric data type.

Returns:

out (array) – an array containing the element-wise results. Each element-wise result must have the same sign as the respective element other_i. The returned array must have a floating-point data type determined by Type Promotion Rules.

Note

Element-wise results must equal the results returned by the equivalent element-wise function remainder().
