Returns the arc sine of a floating-point value.
ASIN(x)
x is a floating-point value such that -1 ≤ x ≤ 1, or is an expression that can be converted to such a value.
ASIN(0.0) /* returns 0.0. */
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.
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.
