ARCSIN

---

Purpose

Arc sine trigonometric function

Synopsis

ARCSIN(value)

Argument

value

One of the following: a constant; a variable; a formula evaluating to a single value; or an XV with only one item

Return value

A value in the range -/2 to +/2.

Example

Given the following matrix items:

Column: A
Column: B
XV    : XVA: A
XV    : XVB: = = = B ^ 2

then the following are all valid uses of the function:

ARCSIN(0.99)
ARCSIN(A)
ARCSIN(B^2)
ARCSIN(SQRT(A))
ARCSIN(XVA)
ARCSIN(XVB)

Further information

value must be in the range -1 to +1. Values outside the range will return zero and produce an appropriate error message. If XSLP_STOPOUTOFRANGE is set then the function error flag will be set.
