The list of methods to do Float Number Create are organized into topic(s).

Method

floattoFloat(short half)
Converts a single precision (32 bit) floating point value into half precision (16 bit). 
switch ((int) half) {
case 0x0000:
    return 0f;
case 0x8000:
    return -0f;
case 0x7c00:
    return Float.POSITIVE_INFINITY;
case 0xfc00:
...
float[]toFloat(short[] arr)
Converts an array of short values to an array of float values. 
int n = arr.length;
float[] converted = new float[n];
for (int i = 0; i < n; i++) {
    converted[i] = arr[i];
return converted;
float[]toFloat(short[] src)
Convert an array of short 's into an array of float '. 
int number = src.length;
float[] dst = new float[number];
for (int j = 0; j < number; ++j) {
    dst[j] = (float) src[j];
return dst;
floattoFloat(String parameter)
to Float 
return Float.parseFloat(parameter);
floattoFloat(String property, float f)
tries to parse the given String into a float value if this fails the default value is returned 
try {
    return Float.parseFloat(property);
} catch (NumberFormatException ex) {
    return f;
FloattoFloat(String s)
to Float 
try {
    return Float.parseFloat(s);
} catch (NumberFormatException e) {
    return new Float(0);
doubletoFloat(String s)
Converts a string into a float 
return Float.parseFloat(s);
floattoFloat(String s)
to Float 
return toFloat(s, -1);
floattoFloat(String str)

Convert a String to a float, returning 0.0f if the conversion fails.

If the string str is null, 0.0f is returned.

 NumberUtils.toFloat(null)   = 0.0f NumberUtils.toFloat("")     = 0.0f NumberUtils.toFloat("1.5")  = 1.5f 
return toFloat(str, 0.0f);
floattoFloat(String str)
to Float 
if (isNumeric(str))
    return Float.valueOf(str);
return 0;
