# RADIANS scalar function

The RADIANS function returns the number of radians for an argument that is expressed in degrees.

The schema is SYSIBM. (The SYSFUN version of the RADIANS function continues to be available.)

- expression
- An expression that returns a value of any built-in numeric data type. If the argument is decimal floating-point, the operation is performed in decimal floating-point; otherwise, the argument is converted to double-precision floating-point for processing by the function.

If the argument is DECFLOAT(`n`), the result is DECFLOAT(`n`); otherwise, the result
is a double-precision floating-point number. The result can be null;
if the argument is null, the result is the null value.

## Example

Assume that host variable HDEG is an INTEGER with
a value of 180. The following statement:

` `**VALUES RADIANS**(:HDEG)

Returns the value +3.14159265358979E+000.
