NAME

SINH, DSINH - Compute hyperbolic sine

SYNOPSIS

SINH ([X=]x)
DSINH ([X=]x)

STANDARDS

Fortran

DESCRIPTION

These are elemental intrinsic functions. SINH is the generic function name. These functions accept the following argument:

x

Must be of type real. See the RETURN VALUES section for information on input data types and return values.

These functions evaluate y= sinh(x) = (ex-e-x) / 2.

NOTES

The names of these intrinsics can be passed as arguments.

Note: The sinh() function has a Linux-equivalent name. Use the man -aname option to show all manual pages matching name within the MANPATH search path. Manual pages are displayed in the order found.

RETURN VALUES

SINH returns the real hyperbolic sine of its real argument.

DSINH returns the double-precision real hyperbolic sine of its double-precision real argument.

EXAMPLES

The following return values occur:

• If x > 709.78, SINH(x) yields infinity.

• If x < -709.78, SINH(x) yields -infinity.

• SINH(NaN) yields NaN.
