Floating-point Math Instructions Section 3-15
Converting to ASCII Text in Scientific Notation
When CIO 000000 is ON in the following example, FSTR(448) converts the
floating-point data in D00001 and D00000 to scientific-notation ASCII text and
writes the ASCII text to the destination words beginning with D00100. The
contents of the control words (D00010 to D00012) specify the details on the
data format (scientific notation, 11 characters total, 3 fractional digits).
3-15-26ASCII TO FLOATING-POINT: FVAL(449)
Purpose Converts a number expressed in ASCII text (decimal or scientific notation) to
a 32-bit floating-point value (IEEE754-format) and outputs the floating-point
value to the specified words.
This instruction is supported by CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.
