ANINT (The GNU Fortran Compiler) (original) (raw)


8.17 ANINT — Nearest whole number

Synopsis:

RESULT = ANINT(A [, KIND])

Description:

ANINT(A [, KIND]) rounds its argument to the nearest whole number.

Class:

Elemental function

Arguments:

A The type of the argument shall be REAL.
KIND (Optional) A scalar INTEGER constant expression indicating the kind parameter of the result.

Return value:

The return value is of type real with the kind type parameter of the argument if the optional KIND is absent; otherwise, the kind type parameter is given by KIND. If A is greater than zero, ANINT(A) returns AINT(X+0.5). If A is less than or equal to zero then it returns AINT(X-0.5).

Example:

program test_anint real(4) x4 real(8) x8 x4 = 1.234E0_4 x8 = 4.321_8 print *, anint(x4), dnint(x8) x8 = anint(x4,8) end program test_anint
