  In this study, the standard IEEE 754 2008 and modulo-based floor functions
for rounding non-integers have been presented. Their effects on the accuracy of
the bilinear interpolation algorithm have been demonstrated. The improved floor
uses the modulo operator in an effort to make each non-integer addend an
integer when the remainder between the multiplicative inverse of the fractional
factor and the numerator is greater than zero. The experiments demonstrated
relatively positive effects with the improved floor function and the
alternativeness to the standard round function.
