DESCRIPTION
Calculates the sine of an expression.
e.g. (assume degrees): SIN( 30 )
Calculates the inverse sine (arcsine) of an expression.
e.g. (assume degrees): ASIN( 0.5 )
This simply toggles through Degrees, Radians, Gradians. The current
setting is indicated in the status line. After setting this parameter,
subsequent input values and the results of expressions are expressed
accordingly.
Converts the current value displayed in the second line, and changes
the status line parameter.
