Description

modulo(a,p) computes the a modulo p.

Standard

(削除) Fortran 95 and later (削除ここまで)(追記) Fortran 95 (追記ここまで)(追記) and later (追記ここまで)

Class

(削除) Elemental function (削除ここまで)(追記) Elemental function (追記ここまで)

Syntax

result = modulo(a, p)

Arguments

• a - Shall be a scalar of type integer or real
• p - Shall be a scalar of the same type and kind as a

Return value

The type and kind of the result are those of the arguments.

• If a and p are of type integer: modulo(a,p) has the value r such that a=q*p+r, where q is an integer and r is between 0 (inclusive) and p (exclusive).

• If a and p are of type real: modulo(a,p) has the value of a - floor (a / p) * p.

In all cases, if p is zero the result is processor-dependent.

Example

program test_modulo
 print *, modulo(17,3)
 print *, modulo(17.5,5.5)
 print *, modulo(-17,3)
 print *, modulo(-17.5,5.5)
 print *, modulo(17,-3)
 print *, modulo(17.5,-5.5)
end program
