sinh

Interface Definition

C interface:

float sinhf(float x);

double sinh(double x);

long double sinhl(long double x);

Fortran interface:

RES = SINHF(X);

RES = SINH(X);

Parameters

Return Value

• The hyperbolic sine y of the radian angle x is returned.
• If the input is ±0, the return value is ±0.
• If the input of sinhf is greater than or equal to 0x1.8p6 (96), the return value is +∞. If the input of sinh is greater than or equal to 0x1.8p9 (768), the return value is +∞.
• If the input of sinhf is smaller than or equal to -0x1.8p6 (-96), the return value is -∞. If the input of sinh is smaller than or equal to -0x1.8p9 (-768), the return value is -∞.
• If the input of sinhf is smaller than 0x1p-13, the return value is x. If the input of sinh is smaller than 0x1p-26, the return value is x.
• If the input is ±∞, the return value is ±∞.
• If the input is NaN, the return value is NaN.

Examples

C interface:

    double pi = acos(-1); 
    // typical usage 
    double a = pi/6, b = 1.0, c = -3*pi/4, d = pi/3; 
    // special handling 
    double e = INFINITY, f = -INFINITY, g = NAN; 
    // print result 
    printf("sinh(pi/6) = %.15f\n", sinh(a)); 
    printf("sinh(1.0) = %.15f\n", sinh(b)); 
    printf("sinh(-3*pi/4) = %.15f\n", sinh(c)); 
    printf("sinh(pi/3) = %.15f\n", sinh(d)); 
    printf("sinh(INFINITY) = %.15f\n", sinh(e)); 
    printf("sinh(-INFINITY) = %.15f\n", sinh(f)); 
    printf("sinh(NAN) = %.15f\n", sinh(g));
