ASIN Function

Purpose

Returns the arc sine of a floating-point value.

Syntax

ASIN(x)

Parameters

x is a floating-point value such that -1 ≤ x ≤ 1, or is an expression that can be converted to such a value.

Description

ASIN(x) returns the arc sine of x expressed in radians, such that -Π/2 ≤ ASIN(x) ≤ Π/2. The result is a floating-point value.

Examples

ASIN(0.0) /* returns 0.0. */

Restrictions

An ASIN operation on Float Decimal data is actually performed using its Float Binary equivalent. Thus, the ranges of the operands and the result are limited to the range of Float Binary data.
