Purpose
Returns the sine of a number. You can call this function from the MapBasic window in MapInfo Pro.
Syntax
Sin( num_expr ) num_expr is a numeric expression representing an angle in radians.
Return Value
Float
Description
The Sin() function returns the sine of the numeric num_expr value, which represents an angle in radians. The result returned from Sin() will be between one and negative one. To convert a degree value to radians, multiply that value by DEG_2_RAD. To convert a radian value into degrees, multiply that value by RAD_2_DEG. The codes DEG_2_RAD and RAD_2_DEG are defined in MAPBASIC.DEF.
Example
Include "mapbasic.def"
Dim x, y As Float
x = 30 * DEG_2_RAD
y = Sin(x)
' y will now be equal to 0.5
' since the sine of 30 degrees is 0.5 See Also:
