Return type: Opaque The square root of either a floating point number or BCD number. For floating point, if x < 0, returns NaN. For BCD, if x < 0, throws an exception.
Returns:
Syntax
define external float function
sqrt value float x
define external bcd function
sqrt value bcd x
Use sqrt to calculate the square root of either
You must include either omfloat.xin or ombcd.xin in your program. Decide whether you want BCD mathematics (excellent for financial calculations) or floating point mathematics (excellent for extremely large numbers).
Floating Point Example:
; Displays the square root of 144 as a floating point number.
include "omfloat.xin"
process
local float x initial {"144"}
local float result
set result to sqrt x
output "result = " || "d" % result || "%n"
BCD Example:
; Displays the square root of 144 as a BCD number.
include "ombcd.xin"
process
local bcd x initial {"144"}
local bcd result
local bcd rounded-result
set result to sqrt x
set rounded-result to round result bankers-nearest 0.01
output "The square root of " || "d" % x || " = " || "d" % rounded-result || "%n"
; Output: "The square root of 144 = 12"
If you take the square root of an integer, the result is coerced into the data type of the library you have included - either a floating point or BCD number.
In an OmniMark program, always surround operators with spaces.
