Class DecimalFloat

java.lang.Object

uk.co.real_logic.artio.fields.ReadOnlyDecimalFloat

uk.co.real_logic.artio.fields.DecimalFloat

All Implemented Interfaces:

java.lang.Comparable<ReadOnlyDecimalFloat>

public final class DecimalFloat
extends ReadOnlyDecimalFloat

Fix float data type. Floats are used for a variety of things, including price.

Must support 15 significant digits, decimal places variable.

Decimal float represents the significant digits using a value field, and the location of the point using the scale field.

See http://fixwiki.org/fixwiki/FloatDataType for details. Examples:

55.36 55.3600 0055.36 0055.3600 .995 0.9950 25 -55.36 -0055.3600 -55.3600 -.995 -0.9950 -25
