Repeat eligibility

REP eligible

Computes the sinh(x) reference over all finite values and signed infinity after DAZ and writes an implementation-bounded S- or D-format approximation under the selected FPTRANSA accuracy contract.

The required FPTRANSA_ACCURACY contract is 0x0021.

Special values

• Infinite or zero source: the result is the source.

Exact anchors

• sinh(+0) = +0

• sinh(-0) = -0

• sinh(infinity) = infinity with the input sign

Required properties

• odd

• monotonically increasing
