4.63.5 Re-entrancy<br />

The function is re-entrant.<br />

4.63.6 Code Example<br />

#include "gflib.h"<br />

tFloat fltIn;<br />

tFloat fltOut;<br />

GFLIB_LIMIT_T_FLT flttrMyLimit = GFLIB_LIMIT_DEFAULT_FLT;<br />

void main(void)<br />

{<br />

// upper/lower limits<br />

flttrMyLimit.fltUpperLimit = 0.5;<br />

flttrMyLimit.fltLowerLimit = -0.5;<br />

}<br />

// input value = 0.75<br />

fltIn = 0.75;<br />

// output should be 0.5<br />

fltOut = GFLIB_Limit_FLT (fltIn, &flttrMyLimit);<br />

// output should be 0.5<br />

fltOut = GFLIB_Limit (fltIn, &flttrMyLimit, Define FLT);<br />

// ##############################################################<br />

// Available only if single precision floating point<br />

// implementation selected as default<br />

// ##############################################################<br />

// output should be 0.5<br />

fltOut = GFLIB_Limit (fltIn, &flttrMyLimit);<br />

4.64 Function GFLIB_LowerLimit_F32<br />
