FLOAT
result = FLOAT (integer expression%
Syntax
This function converts an integer variable into a floating-point variable.
Example error% = 123
result = error% / 1000
This produces an output of [result = 0] since 123 / 1000 = 0 in integer
arithmetic. To produce the correct answer, one of the operands need to be
converted to floating-point.
error% = 123
result = FLOAT(error%) / 1000
This produces the correct answer: result = 0.123
