Function

 FLT

FLT(452) converts the 16-bit signed binary value in S to 32-bit floating-point data (IEEE754-format) and

places the result in R+1 and R. A single 0 is added after the decimal point in the floating-point result.

Only values within the range of -32,768 to 32,767 can be specified for S. To convert signed binary data

outside of that range, use FLTL(453).

Example conversions:

A signed binary value of 3 is converted to 3.0.

A signed binary value of -3 is converted to -3.0.

 FLTL

FLTL(453) converts the 32-bit signed binary value in S+1 and S to 32-bit floating-point data (IEEE754-

format) and places the result in R+1 and R. A single 0 is added after the decimal point in the floating-

point result.

Signed binary data within the range of –2,147,483,648 to 2,147,483,647 can be specified for S+1 and

S. The floating point value has 24 significant binary digits (bits). The result will not be exact if a number

greater than 16,777,215 (the maximum value that can be expressed in 24-bits) is converted by

FLTL(453).

Example Conversions:

A signed binary value of 16,777,215 is converted to 16,777,215.0.

A signed binary value of –16,777,215 is converted to –16,777,215.0.
