sinhfSynopsis#include float sinhf(float x);Description sinhf calculates the hyperbolic sine of x.Fast math librarybehaviorIEC 60559 mathlibrary behaviorPortabilityIf |x| >~ 88.7228, errno (page 247) is set to EDOM and sinhf returns HUGE_VALF.If x is +Infinity, -Infinity, or NaN, sinhf returns |x|.If |x| >~ 88.7228, sinhf returns +Infinity or -Infinity depending upon the sign of x.sinhf conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).sqrtSynopsisDescription#include double sqrt(double val);sqrt computes the nonnegative square root of val. C90 and C99 require that a domainerror occurs if the argument is less than zero. CrossWorks C deviates and always usesIEC 60559 semantics.Special cases If val is +0, sqrt returns +0.If val is -0, sqrt returns -0.If val is Infinity, sqrt returns Infinity.If val < 0, sqrt returns NaN with invalid signal.If val is NaN, sqrt returns that NaN with invalid signal for signaling NaN.Portabilitysqrt conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99) except in thecase of domain errors.sqrtfSynopsisDescription#include float sqrtf(float val);sqrtf computes the nonnegative square root of val.
