integer osIsNotValidNumber(float d)
| |
| Returns 0 (false) if d is a valid float, else returns: 1 - if it is a NaN | |
| Threat Level | This function does not do a threat level check |
| Permissions | Use of this function is always allowed by default |
| Extra Delay | 0 seconds |
| Example(s) | |
// // osIsNotValidNumber Script Example // Author: djphil // string check_number(float value) { integer isValid = osIsNotValidNumber(value); if (isValid == 1) { return (string)value + " is a NaN (" + (string)isValid + ")"; } else if (isValid == 2) { return (string)value + " is a Negative Infinity (" + (string)isValid + ")"; } else if (isValid == 3) { return (string)value + " is a Positive Infinity (" + (string)isValid + ")"; } else { return (string)value + " is a valid float (" + (string)isValid + ")"; } } default { state_entry() { llSay(PUBLIC_CHANNEL, "Touch to see osIsNotValidNumber usage."); } touch_start(integer number) { llSay(PUBLIC_CHANNEL, "llSqrt(10.0) : " + check_number(llSqrt(10.0))); llSay(PUBLIC_CHANNEL, "llSqrt(-10.0) : " + check_number(llSqrt(-10.0))); llSay(PUBLIC_CHANNEL, "-llPow(10.0, 1000.0) : " + check_number(-llPow(10.0, 1000.0))); llSay(PUBLIC_CHANNEL, "llPow(10.0, 1000.0) " + check_number(llPow(10.0, 1000.0))); } } | |
