ComplexFloatingPoint32 Operator (FPScript)
Converts an expression into the 32-bit complex floating point value data type.
Syntax
ComplexFloatingPoint32 Expression
The syntax of the ComplexFloatingPoint32 operator consists of the following elements:
Element |
Description |
|---|---|
Expression |
Any expression. All data types are permitted. |
Remarks
The operator can process scalar values or entire data series and data matrices. If Expression is a data series or a data matrix, then the type conversion takes place on a per-element basis and the result is once again a data series or a data matrix. If a signal, a signal series or a space curve is converted, only the Y component is examined. The result then contains the unchanged X component and possibly the Z component of Expression. If Expression is a list, then the operation is executed for each item in the list and the result is also a list.
The Boolean value TRUE results in the value (1.s, 0.s), and FALSE results in the value (0.s, 0.s). With real data types, the imaginary part is equated to zero. When converting from 64-bit to 32-bit floating point values, the accuracy of the Mantissa is reduced from about 15 digits to about 7 digits. If the exponent of the number for conversion is too large, a void value is output. Strings are interpreted as a value or quantity first and then converted like numerical data. Here the decimal and list separators specified in FlexPro Options are used. The Empty type results in (?s, ?s).
If Expression is a quantity, then its unit is taken and the result is also a quantity.
