double sdlRound(
  1. double x
)

Round x to the nearest integer.

Rounds x to the nearest integer. Values halfway between integers will be rounded away from zero.

Domain: -INF <= x <= INF

Range: -INF <= y <= INF, y integer

This function operates on double-precision floating point values, use SDL_roundf for single-precision floats. To get the result as an integer type, use SDL_lround.

\param x floating point value. \returns the nearest integer to x.

\threadsafety It is safe to call this function from any thread.
