Redondea el argumento de coma flotante arg a un valor entero en formato de coma flotante, utilizando la modalidad de redondeo actual. Si el resultado difiere de arg (es decir, arg no era ya un valor entero), el FE_INEXACT excepción de punto flotante se eleva .
Original:
Rounds the floating-point argument arg to an integer value in floating-point format, using the current rounding mode. If the result differs from arg (i.e., arg was not an integer value already), the floating-point exception FE_INEXACT is raised.
