idivide

Integer division with rounding option

Syntax

C = idivide(A, B, opt)
C = idivide(A, B)
C = idivide(A, B, 'fix')
C = idivide(A, B, 'round')
C = idivide(A, B, 'floor')
C = idivide(A, B, 'ceil')

Description

C = idivide(A, B, opt) is the same as A./B for integer classes except that fractional quotients are rounded to integers using the optional rounding mode specified by opt. The default rounding mode is 'fix'. Inputs A and B must be real and must have the same dimensions unless one is a scalar. The arguments A and B must belong to the same integer class. Alternatively, one of the arguments can be a scalar double, while the other can be any integer type except int64 or uint64. The result C belongs to the integer class of the input arguments.

C = idivide(A, B) is the same as A./B except that fractional quotients are rounded toward zero to the nearest integers.

C = idivide(A, B, 'fix') is the same as the syntax shown immediately above.

C = idivide(A, B, 'round') is the same as A./B for integer classes. Fractional quotients are rounded to the nearest integers.

C = idivide(A, B, 'floor') is the same as A./B except that fractional quotients are rounded toward negative infinity to the nearest integers.

C = idivide(A, B, 'ceil') is the same as A./B except that the fractional quotients are rounded toward infinity to the nearest integers.

Examples

a = int32([-2 2]);
b = int32(3);

idivide(a,b)             % Returns [0 0]
idivide(a,b,'floor')     % Returns [-1 0]
idivide(a,b,'ceil')      % Returns [0 1]
idivide(a,b,'round')     % Returns [-1 1]
