Floating-point Math Instructions
Section 3-15
Variations
Applicable Program Areas
Operand Specifications
Description
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).
Variations
Executed Each Cycle for ON Condition
FLT(452)
Executed Once for Upward Differentiation
@FLT(452)
Executed Once for Downward Differentiation Not supported.
Immediate Refreshing Specification
