Hello,
How is it possible to manage NaN,+Inf, -Inf value in a numeric control with CVI ?.
How can I get the sign bit, the exponent and the mantissa ? I've to translate a four bytes value conform with the IEEE standard ( and so with CVI compiler )into float value but a call to memcpy() seems not to work. My documentation is too poor.
I think I have to do a few traitement before using ldexp() or the formula (-1)^S*2^(exponent-127)*(1.F) with (F :mantissa ).
Can I have a sample of translation between a float and its 4 butes memory ?
