This file provides prototype declarations for the math functions. Most functions are declared using the macro: __MATHCALL (NAME,[_r], (ARGS...)); This means there is a function `NAME' returning `double' and a function `NAMEf' returning `float'. Each place `_Mdouble_' appears in the prototype, that is actually `double' in the prototype for `NAME' and `float' in the prototype for `NAMEf'. Reentrant variant functions are called `NAME_r' and `NAMEf_r'. Functions returning other types like `int' are declared using the macro: __MATHDECL (TYPE, NAME,[_r], (ARGS...)); This is just like __MATHCALL but for a function returning `TYPE' instead of `_Mdouble_'. In all of these cases, there is still both a `NAME' and a `NAMEf' that takes `float' arguments. Note that there must be no whitespace before the argument passed for NAME, to make token pasting work with -traditional. */ #ifndef _MATH_H # error "Never include directly; include instead." #endif /* Trigonometric functions. */ /* Arc cosine of X. */ __MATHCALL (acos,, (_Mdouble_ __x)); /* Arc sine of X. */ __MATHCALL (asin,, (_Mdouble_ __x)); /* Arc tangent of X. */ __MATHCALL (atan,, (_Mdouble_ __x)); /* Arc tangent of Y/X. */ __MATHCALL (atan2,, (_Mdouble_ __y, _Mdouble_ __x)); /* Cosine of X. */ __MATHCALL_VEC (cos,, (_Mdouble_ __x)); /* Sine of X. */ __MATHCALL_VEC (sin,, (_Mdouble_ __x)); /* Tangent of X. */ __MATHCALL (tan,, (_Mdouble_ __x)); /* Hyperbolic functions. */ /* Hyperbolic cosine of X. */ __MATHCALL (cosh,, (_Mdouble_ __x)); /* Hyperbolic sine of X. */ __MATHCALL (sinh,, (_Mdouble_ __x)); /* Hyperbolic tangent of X. */ __MATHCALL (tanh,, (_Mdouble_ __x)); #ifdef __USE_GNU /* Cosine and sine of X. */ __MATHDECL_VEC (void,sincos,, (_Mdouble_ __x, _Mdouble_ *__sinx, _Mdouble_ *__cosx)); #endif #if defined __USE_XOPEN_EXTENDED || defined __USE_ISOC99 /* Hyperbolic arc cosine of X. */ __MATHCALL (acosh,, (_Mdouble_ __x)); /* Hyperbolic arc sine of X. */ __MATHCALL (asinh,, (_Mdouble_ __x)); /* Hyperbolic arc tangent of X. */ __MATHCALL (atanh,, (_Mdouble_ __x)); #endif /* Exponential and logarithmic functions. */ /* Exponential function of X. */ __MATHCALL_VEC (exp,, (_Mdouble_ __x)); /* Break VALUE into a normalized fraction and an integral power of 2. */ __MATHCALL (frexp,, (_Mdouble_ __x, int *__exponent)); /* X times (two to the EXP power). */ __MATHCALL (ldexp,, (_Mdouble_ __x, int __exponent)); /* Natural logarithm of X. */ __MATHCALL_VEC (log,, (_Mdouble_ __x)); /* Base-ten logarithm of X. */ __MATHCALL (log10,, (_Mdouble_ __x)); /* Break VALUE into integral and fractional parts. */ __MATHCAL
