ucSetTrigMode mode

Parameter

mode

The mode argument can be one of the following three constants: uc_Radians (which is the default), uc_Degrees, or uc_Grad.

Remarks

• The trig mode affects the following trigonometric functions: SIN, COS, TAN, and ATAN, as well as any other functions that may be derived from these.
• In the current version, each thread cannot have its own trig mode. Only one mode can be set across all threads

Example:

Visual Basic

ucDefine "Const: pi = atan(1) * 4" ' 3.14159...

' Note: The default mode used for the first two lines below is radians

Print ucEval("sin(90)") ' returns 0.89399...

Print ucEval("sin(pi/2)") ' returns 1

ucSetTrigMode uc_Degrees

Print ucEval("sin(90)") ' returns 1

Print ucEval("sin(pi/2)") ' returns 0.027412...
