Tcast object

Introduction

The TCAST object is available with Solo_Predictor and Solo applications as a data type management object. It allows for conversion between various data types. The object is most often used with instrument or database import objects which may return results in a numerical format other than the PLS_Toolbox standard of double precision. But it can also be useful when the format of the output value needs to be a specific string format.

Invocation

Invocation can be done in a single call by referencing the tcast object along with the method needed and the input needed by that method. For example:

 out = @tcast.toint32(input)

would convert the value or string contained in the "input" object to a 32-bit integer (int32) value.

Conversion Methods

The following methods can be used on most numeric, string, cell, and DataSet object data types:

.tostring() .tochar()	converts to a string (a.k.a. character array)
.tological()	converts to a logical (boolean) value
.todouble()	converts to a double-precision (64-bit) floating point value
.tosingle()	converts to a single-precision (32-bit) floating point value
.toint8() .touint8()	converts to a signed or unsigned 8-bit integer value
.toint16() .touint16()	converts to a signed or unsigned 16-bit integer value
.toint32() .touint32()	converts to a signed or unsigned 32-bit integer value
.tocell()	converts to a cell array (most types convert into a cell array with a single cell element containing all values)
.todataset() .todso()	converts to a DataSet object.
.totranspose()	special does not change data type, but swaps rows and columns of any two-dimensional array (i.e. returns the transpose).
