  22. .SH DESCRIPTION
  23. The functionality described on this reference page is aligned with the
  24. ISO\ C standard. Any conflict between the requirements described here and the
  25. ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.
  26. .P
  27. These functions shall compute the quotient and remainder of the
  28. division of the numerator
  29. .IR numer
  30. by the denominator
  31. .IR denom .
  32. If the division is inexact, the resulting quotient is the
  33. .BR long
  34. integer (for the
  35. \fIldiv\fR()
  36. function) or
  37. .BR "long long"
  38. integer (for the
  39. \fIlldiv\fR()
  40. function) of lesser magnitude that is the nearest to the algebraic
  41. quotient. If the result cannot be represented, the behavior is
  42. undefined; otherwise, \fIquot\fP\ *\ \fIdenom\fP+\fIrem\fP shall equal
  43. .IR numer .
  44. .SH "RETURN VALUE"
  45. The
  46. \fIldiv\fR()
  47. function shall return a structure of type
  48. .BR ldiv_t ,
  49. comprising both the quotient and the remainder. The structure shall
  50. include the following members, in any order:
  51. .sp
  52. .RS 4
  53. .nf
  55. long   quot;    /* Quotient */
  56. long   rem;     /* Remainder */

  61. The
  62. \fIlldiv\fR()
  63. function shall return a structure of type
  64. .BR lldiv_t ,
  65. comprising both the quotient and the remainder. The structure shall
  66. include the following members, in any order:
  67. .sp
  68. .RS 4
