Data types: float
Represents a floatingpoint number with singleprecision.

Discussion
The floatingpoint numbers are expressed in the decimalpoint notation with an optional + or  sign put in front of the number and an optional exponent after a trailing e. The literals can be used within expressions wherever a float operand is expected. The type name float, in turn, is designated to be used in declarations of data members. For example:
var float angle = 90.0; var float voltage = 5.13; var float current = 1.3e3;
Floating point precision
Generally, the programming language Chora assumes the float data type and the associated operations as being performed with at least 32bit single precision. This may differ on target systems supporting the floatingpoint data type with double precision (64bit).
Instant properties
With the following instant properties you can evaluate status or the value of a float operand:
Instant property name 
Short description 

Represents the absolute value of the given float operand. 

Represents the next highest integer value of a float operand. 

Represents the next lowest integer value of a float operand. 

Represents the fractional part of a float operand. 

Verifies the Infinity (+INF or INF) status of a float operand. 

Verifies the Negative Infinity (INF) status of a float operand. 

Verifies the Positive Infinity (+INF) status of a float operand. 

Verifies the Not a Number (NAN) status of a float operand. 

Represents the float operand rounded to the next lowest or highest integer value. 

Represents the float operand rounded by removing the fractional part. 
Arithmetic operations
You can combine a float operand with other operands to arithmetic expressions. The following table provides an overview of the possible operations:

Type conversions
Chora reacts sensitive when mixing operands of different data types within an operation. To avoid compiler warnings or even errors you can convert the affected operands explicitly by using following conversion operations:
Conversion operations with signed integers 

Conversion to or from a signed or unsigned integer value. 
Formatting a string from a floatingpoint number. 
Parsing a string as a floatingpoint number.
