Sin

The Sin functions return the sine of an angle.

angle

is the angle, expressed in radians, whose sine is returned.

Return Value

The Sin functions return the sin of angle. The return value is in the range:

-1.0 less than or equal to sin(

angle) less than or equal to 1.0

Sinh

The Sinh functions return a hyperbolic sine.

number

is the number whose hyperbolic sine is returned.

Return Value

The sinh functions return the hyperbolic sine of number. The return value is:

exp( number ) - exp( -number )

Considerations

An arithmetic fault occurs if there is an overflow in any intermediate calculation.

REAL(32) PROC RTL_Sin_Real32_( angle );

REAL(32) angle; ! in TNS only

REAL(64) PROC RTL_Sin_Real64_( angle );

REAL(64) angle; ! in TNS only

REAL(32) PROC { CRE_Sinh_Real32_ } ( number );

{ RTL_Sinh_Real32_ }

REAL(32) number; ! in TNS only

REAL(64) PROC { CRE_Sinh_Real64_ } ( number );

{ RTL_Sinh_Real64_ }

REAL(64) number; ! in TNS only
