NAME

ICEIL - Returns integer ceiling of a rational number

SYNOPSIS

i=ICEIL(j, k)

IMPLEMENTATION

Cray Linux Environment (CLE)

DESCRIPTION

ICEIL is an integer function that returns the integer ceiling of a rational number formed by two integer parameters.

All arguments must be of default kind unless documented otherwise. The default kind is KIND=4 for integer arguments.

The following is a list of valid arguments for this routine.

j

The numerator of a rational number.

k

The denominator of a rational number.

The value of function i is the smallest integer larger than or equal to j/k.

If the Fortran program that calls ICEIL is compiled with the -s default64 option, specify the arguments as INTEGER(4) arguments or include the -A FTN_LIB_DEFINITIONS as a compilation option. The FTN_LIB_DEFINITIONS module provides a generic interface for the ICEIL function. The compiler will choose the entry point for ICEIL by checking the types of the arguments.
