In SQLite, the cos() function returns the cosine of a value specified in radians.

Syntax #

cos(x)Copy

Arguments #

x

x is a number, an expression, or a table column that you want to calculate the cosine.

Return Type #

real

The function returns the cosine of x in radians. If x is NULL, the function returns NULL.

If x is a string, the cos() function will convert it into a number before calculating the cosine. If the conversion fails, the cos() function returns NULL.

The following example uses the cos() function to calculate the cosine of zero (0):

SELECT cos(0) result;Copy
