.float/.bfloat/.double/.efloat/.tfloatDirectives ReferenceSyntax .float value [,..., value n ].bfloat value [,..., value n ].double value [,..., value n ].efloat value [,..., value n ].tfloat value [,..., value n ]DescriptionThe .float directive places the floating-point representation of a single floating-pointconstant into two words in the current section. value must be a floating-pointconstant. Each constant is converted to a floating-point value in 32-bit IEEEfloating-point format.The IEEE floating-point format consists of three fields: A 1-bit sign field (s) An 8-bit biased exponent (exponent) A 23-bit normalized mantissa (mantissa)15 14 7 6 0s exponent mantissa15 0mantissa.bfloat.efloatThe .bfloat directive format is slightly different in that it has a 16-bit exponentand both a high and low mantissa:15 0exponent15 0mantissa (high)15 0mantissa (low)ExampleHere is an example of floating-point directives.Source file:.ds0400h.bfloat 1.5,3,6.bfloat –1.5,3,6.efloat 1.5,3,6.end5-18
