sdlTrunc function stdinc

double sdlTrunc(double x)

Truncate x to an integer.

Rounds x to the next closest integer to 0. This is equivalent to removing the fractional part of x, leaving only the integer part.

Domain: -INF <= x <= INF

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

This function operates on double-precision floating point values, use SDL_truncf for single-precision floats.

\param x floating point value. \returns x truncated to an integer.

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