Returns the cosine value for number, where number is the angle size, expressed in degree [D], radian [R], or grade [G] units.

Parameters:

number

The angle size, expressed in degree [D], radian [R], or grade [G] units.

precision

The precision of the calculation. If a value is not specified, the precision of the calling Rexx activity is used. If the precision exceeds 16 digits, the call will fail.

D

Indicates that the angle size is expressed in degrees. This is the default.

R

Indicates that the angle size is expressed in radians.

G

Indicates that the angle size is expressed in grades.
