RTOI – Real to integer number conversion

Block SymbolLicensing group: STANDARD

Function Description
The RTOI block converts the real number r to a signed integer number i. The resulting rounded value is defined by:

where $round$ (r) stands for rounding to the nearest integer number. The number of the form $n$ +0.5 ( $n$ is integer) is rounded to the integer number with the higher absolute value, i.e. $round (1.5) = 2$ , $round (- 2.5) = - 3$ . Note that the numbers $- 2147483648$ and $2147483647$ correspond with the lowest and the highest signed number representable in 32-bit format respectively (0x7FFFFFFF and 0x80000000 in hexadecimal form in the C language).

Input
