1. ANSI C requires an integer cast of a double argument to correctly use an integer conversion specifier like d. A similiar conversion is required when using such a specifier with non-integral MATLAB values. Use FIX, FLOOR, CEIL or ROUND on a double argument to explicitly convert non-integra...
When converting a floating-point number to an integer, thecastfunction rounds the number to the nearest integer. If the floating-point number has a fractional part of exactly 0.5, then it rounds away from zero to the integer with larger magnitude. ...
